Late-Presentation Cross-Ectopia Testes in an Infertile Man 31-Years Old

ABSTRACT

We present a 31-year-old man with transverse testicular ectopia of the left testis. He presented to our surgical outpatient department with right scrotal swelling, originally diagnosed as an obstructed hernia, and an impalpable testis in the left scrotum. We performed a right herniotomy on the patient and found a large lobulated left testis and normal right testis in the right scrotum. Diagnosis of transverse testicular ectopia was made on the operation table, as the man originally came for repair of obstructed right inguinal hernia. This is the first case of transverse testicular ectopia we have come across since 1966.

Utilization of the NMP22 BladderChek Urine Test as an Adjunct to Atypical Cytology in the Detection of Bladder Cancer Recurrence

ABSTRACT

Objective: To assess the performance of the NMP22® BladderChek® (NMP22-BC) urine test compared with cytological and histological findings for detecting bladder cancer recurrence in patients with a prior history of bladder cancer.

Methods: A prospective study was performed, evaluating a total of 112 urine samples from 67 patients. These samples were obtained prior to cystoscopy and were analyzed with the NMP22-BC. The results were compared against those of voided urine cytology (VUC) and cystoscopy.

Results: Of the 112 samples, there was a total of 27 recurrences (24.1%). The overall sensitivity of NMP22-BC alone was 33%, VUC with malignant or suspicious specimens alone was 37%, and the two methods combined was 46%. The specificity of NMP22-BC alone was 92%, VUC alone was 99%, and both methods combined was 92%. The detection rate of bladder cancer recurrence in high-grade tumors increased from 50% for NMP22-BC alone and 43% for VUC alone, to 64% when both tests were used in combination. The detection rate of recurrence for stages Ta, T2, and CIS was also significantly increased when NMP22-BC and VUC were used in combination. The overall positive and negative predictive values were 68% and 84% respectively. Inclusion of atypia as positive for recurrence (VUC+A) increased the overall sensitivity of cytology to 72% but decreased the specificity to 64%. However, in cases where atypical cytology was confirmed with positive NMP22-BC, the sensitivity of the combination was 46% and specificity was 100%.

Conclusion: NMP22® BladderChek® is a valuable addition to voided urine cytology for detection of high-risk lesions. Our study shows that once atypical cytology is confirmed by NMP22-BC, the specificity is 100%. Furthermore, the sensitivity of this combination is superior to that of malignant or suspicious cytology alone.

Perforating Intravesical Intrauterine Devices: Diagnosis and Treatment

ABSTRACT

Background: Intravesical foreign bodies are a reported problem with variable natures. Rarely, it is reported to be an intrauterine device (IUD) that perforates through both the uterine and the vesical walls to lie within the urinary bladder.

Objective: We report our experience with 6 cases of IUDs perforating into the urinary bladder.

Methods: Over 5 years, a total of 6 patients with IUDs perforating to the bladder presented to our facility complaining of LUTS and positive for microscopic hematuria of variable duration. Large, 4- to 5-cm stones were found in 2 patients and were removed via cystolithotomy. IUDs were removed from 3 patients via cystolitholapaxy and endoscopic extraction, and 1 partially perforating IUD with no stone formation was treated via extraction of the device per vagina.

Results: All procedures went well with no complications. Patients received urinary drainage for 1 week postoperatively.

Conclusion: IUD perforation to the bladder, with or without stone formation, is a rare event that can be diagnosed and treated easily with minor procedures and minimal complications, provided that the urologist kept the condition in mind.

Nocturia: Pathogenesis and Diagnosis From a New Viewpoint

ABSTRACT

Nocturia, which affects general health and quality of life, is a symptom often observed not only in patients with benign prostatic hyperplasia, but in the elderly of both genders as well. There are 5 causes of nocturia: (1) nocturnal polyuria, (2) reduction of nocturnal bladder capacity, (3) a combination of 1 and 2, (4) global polyuria, and (5) sleep disorders. To understand the pathogenesis of nocturia, it is important to investigate different factors for each cause. For nocturnal polyuria (1), it is important to investigate excessive fluid intake, hypertension, circadian rhythm of arginine vasopressin (AVP), and cardiovascular conditions based on brain natriuretic peptide (BNP) levels in plasma. For reduction of nocturnal bladder capacity (2), blood pressure and plasma concentrations of melatonin and glycine must be measured. Complicating systemic diseases such as diabetes mellitus, diabetes insipidus and polydipsia can lead to global polyuria (4), and sleep disorders (5) are defined by the quality of sleep, including conditions of arousal and hypnagogic disorders. The purpose of this article is to review the pathogenesis and diagnosis of nocturia, particularly by focusing on other causes than urological fields, which might lead to a better understanding of nocturia. To diagnose and make a therapeutic plan for nocturia, a modified bladder diary, International Prostate Symptom Score (IPSS), King’s Health Questionnaire (KHQ), Pittsburgh Sleep Quality Index (PSQI), and a sleeping diary are useful and should be combined with an interview and urological examination.

Renal Cell Carcinoma with Synchronous Gallbladder Metastasis Treated with Laparoscopic Radical Nephrectomy and Cholecystectomy in the Same Setting

ABSTRACT

Renal cell carcinoma (RCC) with gallbladder metastasis is a very rare entity, whether as a synchronous or metachronous lesion. Additional ancillary immunohistochemical tests may be required to make the diagnosis. We report the case of a 66-year-old woman with primary RCC and a synchronous gallbladder metastasis, who underwent laparoscopic radical nephrectomy and cholecystectomy in the same setting. Gallbladder histopathology revealed clear cell RCC, similar to the primary tumor. With positive immunostaining of the tumor for CA-IX, she has responded well to interleukin-2 immunotherapy.

Early and Late Complications in Living Donor Nephrectomies

ABSTRACT

Between May 2000 and May 2003, 300 living donor nephrectomies were performed through an extraperitoneal flank approach. The majority of complications were minor, easily diagnosed, and managed during hospital stay. Early postoperative complications were reported in 22 (7.33%) cases. Of these, wound complications were the most common, accounting for 10 (3.33%) complications, followed by 8 (2.67%) pulmonary complications. The most serious postoperative complication was frank wound bleeding necessitating wound exploration in 2 (0.67%) patients. Postoperative urinary retention was reported in 3 (1%) patients, and deep venous thrombosis was reported in 1 (0.33%). Urinary tract infections were diagnosed in 15 (5%) patients, and there was a stricture of the urethra in 1 (0.33%) patient. All cases were diagnosed and managed carefully. Follow-up lasted for 18-36 months. Late postoperative complications were reported in 28 (9.33%) patients, and urinary calculi were found in 12 (4%) donors.

We proved that retroperitoneal flank nephrectomy is a safe approach for the donor, with acceptable early and late surgical complications. It provides optimal allografts for transplantation, and there were no complications related to non-drain fixation.

Treatment of Symptomatic Simple Renal Cysts by Percutaneous Aspiration and Ethanol Sclerotherapy

ABSTRACT

Introduction: Although simple renal cysts are usually asymptomatic and discovered incidentally, treatment is undoubtedly still indicated in symptomatic patients. Significant pain, compression of the pelvicalyceal system, and possibly related hypertension or hematuria are indications for intervention.

Patients and Methods: Our study included 17 patients (11 men and 6 women, mean age of 46 years) with symptomatic simple renal cysts. The main presentation was renal pain in 9 patients, followed by hypertension in 5 and hematuria in 3. The patients were treated by ultrasonography (US)-guided percutaneous aspiration and with an injection of 95% ethanol. Patients were evaluated one month postoperatively and every six months thereafter by clinical assessment, US, and intravenous urography. Success was defined as complete when there was total ablation of the cyst and partial when there was a recurrence of less than half the original cyst volume and a resolution of symptoms. Failure was defined as the recurrence of more than half of cyst volume or persistent symptoms.

Results: After aspiration and ethanol sclerotherapy, there was microscopic hematuria in 2 patients and low-grade fever (< 38.3°C) in another 2, but no major complications. During a mean follow-up of 19 months (range 14–40), there was complete cyst ablation in 15 (88%) patients and partial resolution in 2 (12%). Pain disappeared or was much improved in all patients. Hypertension was well controlled with no medication in 4 previously hypertensive patients, and hematuria disappeared in all 3 affected patients.

Conclusion: Ethanol sclerotherapy for symptomatic simple renal cysts is simple, minimally invasive, and highly effective. We recommend it as the first therapeutic option in these patients.

Evaluation of Urinary Bladder Function in Patients with Lumbar Intervertebral Disk Protrusion

ABSTRACT

Background: Lower urinary tract symptoms (LUTS) have been described in patients with bladder dysfunction due to prolapsed lumbar disks. Progressive compression caused by lumbar disk herniation leads to loss of bladder sensation and voiding difficulty due to an acontractile detrusor.

Objective: Our objective in this study was to determine the cystometric findings in patients with lumbar intervertebral disk protrusion (LDP).

Methods: 80 patients with lumbar disk protrusion were included in this study. Their mean age was 39.9 years (26-64), 58 patients (72.5%) were males, and 22 (27.5%) were females. They were divided into two groups according to their urodynamic results: patients in Group I had normal detrusor function (52 patients), and patients in Group II had abnormal detrusor activity (28 patients). Thorough histories and clinical examinations, including general examinations, urological examinations, and neurological examinations, were done for each patient. Uroflowmetry and cystometry were done for the evaluation.

Results: 18 out of 28 patients in Group II had acontractile detrusor, 7 patients had detrusor underactivity, and 3 patients had neurogenic detrusor overactivity. 35 patients (43.75%, 12 from Group I, 23 from Group II) presented with urological symptoms, and all had more than one symptom. Of the 28 patients in Group II, 23 reported LUTS suggestive of bladder outlet obstruction, and only 5 patients in Group II showed no urological symptoms (P<0.05). There was a statistically significant difference between the two groups regarding multiple LDP affections (P<0.05). There was a high percentage of non-contained LDP in Group II with a statistically significant difference (P<0.05).

Conclusion: Acontractile detrusor represents the most common cystometric finding in patients with LDP. Neurogenic detrusor overactivity may occur in the initial stage of the disease. Patients with multiple, diffuse, and non-contained LDP are more liable to have abnormal detrusor activity.

Laparoscopic Partial Nephroureterectomy for Duplex Kidney and Ureter with Megaureter Serving a Hydronephrotic Excluded Upper Pole: A Case Report

ABSTRACT

Introduction: Complete duplication of the collecting system is one of the most common congenital urologic anomalies that should be oriented with nephroureterectomy when symptomatic with urinary tract infection or flank pain. Until recently, nephroureterectomy involved a flank incision with significant morbidity and prolonged recovery time. In the last few years, there have been a few reports of partial nephroureterectomy, particularly in the pediatric population.

Case Presentation: A 25-year-old woman presented to our consult with a history of recurrent right pyelonephritis and a right duplicated kidney and ureter associated with atrophy of the hydronephrotic upper-pole and dilation of the entire respective ureter. Voiding Cystourethrography showed no vesicoureteral reflux. She elected to undergo laparoscopic transperitoneal upper-pole nephroureterectomy. There were no postoperative complications, and the cosmetic result was excellent.

Conclusion: To our knowledge this is one of the few reports of laparoscopic partial nephroureterectomy done in adults. This seems to be a safe and effective technique to be performed in adults, with admirable cosmetic and functional results.

Study of Urinary Crystals for Type 1 Diabetics

ABSTRACT

Introduction: Diabetes mellitus is a common public health problem due to the seriousness of its complications. Because of the potential harm to the kidneys of diabetic patients, preventive and therapeutic measures should be taken against the various types of lithiasis.

Materials and Methods: This survey included 116 type 1 diabetics. First morning urine samples were examined with a polarized light microscope for qualitative and quantitative analysis of crystalluria.

Results: The calcium oxalates were more abundant in both genders compared to the other crystalline species, with a frequency of 76.7% at direct examination and 82.4% at +4°C. The total frequency of purine crystalluria was 22.0% at direct examination.

Conclusion:The crystalluria observed in type 1 diabetics showed the predominate prevalence of the oxalocalcic type (Weddellite) crystals with a frequency of 64.5%, followed by Whewellite with a frequency of 15.0%. The high percentage of the purine crystalluria in diabetics gives information about dangers to clinicians and experts.

Open Surgery in the Management of Multiple and Staghorn Kidney Stones: Its Role in the Era of Minimally Invasive Techniques

ABSTRACT

Background: The use of minimally invasive techniques in the treatment of staghorn and multiple renal stones has overshadowed the open techniques in the past two to three decades. In this study, we reevaluate the role of open techniques in the management of these conditions.

Objective: To compare the role of open techniques versus combined percutaneous nephrolithotomy (PCNL) and extracorporeal shock wave lithotripsy (ESWL) in the management of staghorn and multiple renal stones.

Methods: Between 1999 and early 2005, a total of 208 patients were operated upon: 111 patients with 118 renal units underwent open-technique surgery, and 97 patients with 106 renal units underwent combined PCNL and ESWL. Operative time, operative cost, blood loss, stone-free rate, use of single or multiple sessions, hospital stay, complications, total cost, and time to return to ordinary activities were calculated and plotted in a database, analyzed, and compared for the two groups of patients.

Results: Operative time for the open group was significantly less than the PCNL group, as most of the latter needed multiple sessions of PCNL and ESWL, raising the hospital stay, the operative cost, and the total hospital cost. In the open group, 106 (89.8%) patients were stone free in a single session, and only 12 (10.2%) needed ESWL sessions. In the PCNL group, 88 (83%) patients were stone free after the first session, a statistically significant difference. However, the time needed for convalescence was significantly less for the PCNL group.

Comparing the complication rate for both groups, we found that the open group had less incidence of colonic injury, AV fistula, and urinary leakage, which reflected on the length of hospital stay and cost. However, the open group had more incidence of blood loss and pneumothorax, comparable incidence of sepsis, and needed more time to return to ordinary activity compared to the PCNL group.

Conclusion: Open techniques are still a viable option that should be considered when treating patients with complex multiple and staghorn renal stones, especially regarding their cost-effectiveness in the face of limited resources in developing countries.

A Randomized Comparison of Two Synthetic Mid-Urethral Tension-Free Slings

ABSTRACT

Objective: A randomized prospective comparison of two synthetic mid-urethral tension-free slings was undertaken at a university hospital to evaluate clinical efficacy, complication rates, and ease of procedure and training residents.

Methods: Between January 2004 and September 2005, 96 women with stress urinary incontinence were consecutively assigned to Gynecare TVT® or Boston Scientific Lynx® mid-urethral slings (n=48 in each group) at the University of Nebraska Medical Center. Both groups were similar in mean age, parity, weight, preoperative post-void residual, cystometric capacity, flow rate, and urethral closure pressures. Postmenopausal status and previous incontinence surgery rates were also comparable. Intraoperative complications, ease of trocar placement, postoperative voiding difficulties, subjective and objective cure rates, and postoperative interventions were assessed. During statistical analysis, p<0.05 was used as cut-off for significance.

Results: Half of the patients in both groups underwent multiple procedures. There were two (4%) trocar injuries with the TVT and three (6%) with the Lynx (p=.21). Early postoperative voiding dysfunction was 21% (10 patients) for the TVT group versus 15% (7 patients) for the Lynx (p<0.001), whereas prolonged catheterization for two weeks was similar at 4% (2 patients) for both. UTI rate for the TVT was 10% (5 patients) and 13% (6 patients) for Lynx (p=0.02). Subjective cure rates were 94% (45 patients) and 92% (44 patients), respectively (p=.08). Urethral closure pressure <14 cm H2O was the identifiable risk for objective failure. Objective cure rates were 96% (46 patients) for the TVT and 94% (45 patients) for the Lynx (p=.12), suggesting that some subjective failure was likely due to de novo bladder overactivity. One sling in the Lynx group was removed for skin cellulites, and one sling slit in TVT group was removed for voiding dysfunction due to duplicated ureter on the left side.

Conclusion: Despite similar efficacy, complication rates, and failure rates, the incidence of postoperative voiding difficulties was better with Lynx, due likely to the mid-urethral seal. However, it was difficult to place the Lynx trocar in patients with prior surgeries, probably due to the blunt needle and notch. An increased rate of vaginal graft exposure was seen with the Lynx. Residents favored the Lynx trocar because of its light weight and greater stability.

Letter from the Editor - June 2008

Dear Colleagues,

The 4th International Consultation on Incontinence (ICI) will be held in Paris July 5-8, 2008. The organizers of this workshop have summoned the world´s leading experts in urology, gynecology and urodynamics to present and discuss the most recent advances in the field, including epidemiology, basic science, and treatment. However, the purpose is not only to review the current state of knowledge on incontinence, but also to propose strategies for the practical diagnostic and therapeutic management of the disorders following the evidence based medicine principles. Additionally the purpose is to propose validated standard international instruments to evaluate incontinence, and to help standardize response criteria and recommendations for clinical research on incontinence.

This broad scope of the workshop is reflected in the abstracts of the posters that will be presented at the meeting and which this first issue of Urotoday International Journal (UIJ) is proud to publish with exclusivity. The abstracts comprise not only different aspects of the overactive bladder such as treatment, epidemiology, basic science, but also summarize recent advances in the areas of stress incontinence, pelvic floor disorders and prolapse. Methods, technical and diagnostic aspects of incontinence, as well as of treatment, are also covered. The aim of UIJ is to elevate the access to relevant urology science to professionals around the world and to make this scientific information available to a wide audience. We believe that there is a good chance that this aim will be fulfilled for these abstracts, since UIJ currently reaches over 60,000 professionals in urological diseases.

It is our hope that all professionals in the fields of incontinence research and management, both experienced and newcomers, will benefit from these abstracts, and become inspired towards further efforts.

Kind regards,
Karl-Erik Andersson

Delayed Extravesical Shrapnel Migration into the Urinary Bladder: A Case Report and Review of a Rare Clinical Entity

ABSTRACT

Foreign objects in the urinary bladder may result from urethral passage by the patient, extraneous trauma or ballistic injury, or even more rarely as a result of spontaneous migration of retained metal fragments from prior trauma. In the former acute trauma settings, the patient usually presents for prompt evaluation and treatment. In the latter setting, the patient may present in a delayed fashion with nonspecific urologic complaints. We present an unusual case report involving the extremely delayed migration of a retained piece of shrapnel into the urinary bladder.

Bladder Pharmacology and Treatment of Lower Urinary Tract Symptoms: Recent Advances

ABSTRACT

Since the pathophysiology of Lower Urinary Tract Symptoms/Overactive Bladder (LUTS/OAB) is multifactorial, there are many potential targets for future drugs, as identified in preclinical investigations. However, it is difficult to predict what principles can be applied clinically. The mere finding that a drug affects the LUT in a desirable direction seldom motivates speculations like “this may be a new way of treating LUTS/OAB”. For several of the potentially useful drugs, published clinical studies have demonstrated the proof of principle. This review will discuss the pharmacology of and clinical experiences with some of these drugs.

Telementoring in Urodynamics: Initial Experience

ABSTRACT

Background: The development of computer-based equipment for diagnostic and therapeutic purposes has evolved considerably in the past few decades. The ability to remotely operate various devices has led physicians to provide off-site assistance in different areas of medicine.

Objectives: The aim of this paper is to share the authors’ initial experience with remote-access urodynamic telementoring. The main focus is in the possibility of using this method for teaching purposes.

Methods: A combination of software installed in both the equipment and the remote computer allowed mentors to participate in the test both peri- and post-procedurally. The use of a webcam allowed visualization and dialog with the patient, and more than one observer could monitor technicians performing the test. Password-protected access warranted patient privacy.

Results: The authors remotely monitored over one hundred urodynamic studies performed in two centers during the past 6 months. The results were satisfactory concerning remote visualization and reporting of tests. The use of this technology adds very little cost in terms of both equipment and operating procedures.

Conclusions: Telementoring in urodynamics may open new possibilities for the teaching and spreading of this important urologic diagnostic tool.

Complicated Cataract Surgery in Patients Receiving Alpha-Blockers for Benign Prostatic Hyperplasia

ABSTRACT

Background: Of adults 50 to 80 years old, 29% of men in Europe and 34% of men in the United States have moderate to severe lower urinary tract symptoms. Alpha-blocker medications are the first line of therapy for men with these urinary symptoms. Among this population, cataracts are similarly common. The “intra-operative floppy iris syndrome” cataract surgery complication has been reported in men using alpha-blockers.

Objective: To assess the frequency of cataract surgery complications arising from alpha-blocker therapy in a large patient population.

Design, Setting, and Participants: We retrospectively reviewed the outcomes of 2666 consecutive adults who underwent elective unilateral cataract surgery. The surgeries took place between 2000 and 2005 at both a large university hospital system and a Veteran’s Association medical center. Medical records were assessed for medication use, and operative records were reviewed for evidence of difficult procedures.

Results: The risk of complicated cataract surgery was 14.9% in patients using alpha-blockers, approximately 50% higher than those not receiving this medication (9.5%) (p=0.003). The increased rate of complicated surgeries was restricted primarily to patients over 65 years of age, as 15.6% of surgeries performed on these patients resulted in complicated surgery (p=0.03). There was no statistically significant increase in the rate of complicated surgeries in patients under age 65 who were using alpha-blockers (p>0.05).

Conclusions: If possible, alpha blocker medications should be discontinued prior to eye surgery in older patients.

Differences in the Secretory Activity of the Atypical Adenomatous Hyperplasia and Low-Grade Prostatic Adenocarcinoma

ABSTRACT

Background: Atypical adenomatous hyperplasia (AAH) is a small, glandular proliferation that has histological similarities to Gleason grade 1 and 2 prostatic adenocarcinoma (PACG 1, 2). There are no distinct histomorphological criteria distinguishing these two lesions from each other and other small glandular proliferations. It is necessary to define histological criteria, as treatment approaches are different for these lesions.

Objectives: This study’s aim was to evaluate the differences in the secretory properties of AAH and PACG 1, 2. We searched for intraluminal crystalloids, corpora amylacea, mucin, and eosinophilic material.

Subjects and Methods: 105 totally embedded radical prostatectomy specimens containing 11 AAH (22 foci) and 15 PACG 1, 2 (22 foci) lesions were evaluated. Basal cell specific antikeratin was applied. We accepted that PACG 1, 2 lesions do not contain basal cells, and we grouped lesions as AAH and PACG 1, 2 based on this opinion. The luminal contents were evaluated by PASAB2, 5 and PTAH.

Results: We found differences between the AAH and PACG 1, 2 lesions for some parameters, including crystalloids, corpora amylacea, and mucin. We found similar properties between the two lesions for eosinophilic material.

Conclusion: In a difficult case, evaluation of the luminal content features may be helpful, but the diagnosis must be supported by immunohistochemistry.
