Letter from the Editor - June 2011

Dear Colleagues,

This issue marks the beginning of the fourth year for UroToday International Journal, and we have continued successfully to achieve our primary goal to elevate access to urology science for professionals around the world. This could not have been achieved without the dedication of both our authors and reviewers.

The current issue contains a variety of articles, many of which should be of high interest to the professional community. Hajebrahimi et al. evaluated the effect of changes in voiding position on uroflowmetric findings of young, healthy male vounteers, and found no statistically significant differences between the standing, sitting, or squatting voiding positions for any of the measured urodynamic outcome parameters: peak flow rate (Qmax), average flow rate, time to peak flow, flow time, and voided volume. Bhat et al. studied the effects of the transurethral catheter comparing free uroflow versus pressure-flow on their outcome measures: maximum flow (Qmax), average flow rate, voiding time, time to Qmax, and flow acceleration. With a small sample size they were able to show an obstructive effect of an in situ 5 Fr urethral catheter during pressure-flow studies, a finding that needs to be confirmed by a randomized prospective investigation. Karami et al studied prospectively the prevalence of acquired renal cystic disease (ARCD) in patients with end-stage renal disease receiving hemodialysis, and they conclude that patients who are on long-term hemodialysis should be monitored for the development of ARCD. Ahmed Shelbaia evaluated the results of early endoscopic management of posttraumatic posterior urethral stricture by visual internal urethrotomy (VIU), and conclude that early endoscopic urethral realignment surgery is a safe procedure with few complications. Miyaoka et al. report the first-year follow-up results on the safety and efficacy of the Ophira Mini-Sling System, which uses a minimally invasive, midurethral low-tension tape that is anchored to the obturator internus muscles bilaterally at the level of the tendinous arc by a single vaginal incision. They conclude that the system appears to be an effective, minimally invasive option for the treatment of stress urinary incontinence.

We are devoting a larger-than-normal portion of this issue to the publication of case reports. Such cases often provide insight into rare conditions, reminding us to be more vigilant during differential diagnosis or more open to alternative ways of managing a given disorder. de Leon et al. present the first known case of atraumatic bladder rupture in an adult with Ehlers-Danlos syndrome. The authors attribute the spontaneous rupture to a weakened bladder wall and caution against overextending the bladder during cystoscopic procedures with these types of patients. Bhat et al. describe a 24-year-old married, phenotypic female. She presented with an inability to conceive and no knowledge of having androgen insensitivity syndrome. The authors discuss the complex physical and psychological issues involved in the management of patients with this disorder. Khan et al. describe a 44-year-old patient with an appendicular mass that was discovered at the beginning of living-donor kidney transplant surgery. Traditionally, the transplant would be aborted and rescheduled following recovery from an appendectomy. However, the authors detail the sequence of events that enabled them to successfully perform both surgical procedures in the same session, and discuss the circumstances when this approach is unlikely to be feasible.

It is our primary goal to publish original studies, and we encourage you to submit the results of clinical or basic science research in all areas of urology. I personally thank the authors and reviewers for their valuable contributions to this journal issue. 

 

Sincerely,

Spontaneous Bladder Rupture in a Patient With Adult Ehlers-Danlos Syndrome Without Bladder Diverticulae

ABSTRACT

Ehlers-Danlos syndrome (EDS) is a group of inherited connective tissue disorders due to mutations of the connective tissue genes. It is characterized by the triad of skin hyperelasticity, joint hypermobility, and connective tissue fragility. A 50-year-old man presented with acute clot hematuria and dysuria with no preceding trauma. He had a background of EDS and chronic lower urinary tract symptoms secondary to benign prostatic hyperplasia. The diagnosis of extraperitoneal bladder rupture was made on imaging. This is the first known reported case of spontaneous bladder rupture in an adult with EDS, although there have been 2 reports of children who spontaneously ruptured a bladder diverticulum. We suggest that patients with EDS and evidence of bladder outlet obstruction should be managed closely. Early surgical intervention may be needed. Care should also be taken so that the bladder is not overdistended during cystoscopic procedures.

Androgen Insensitivity Syndrome: Case Report With Review of the Literature

ABSTRACT

Androgen insensitivity syndrome (AIS), also known as testicular feminization, encompasses a wide range of phenotypes that are caused by numerous different mutations in the androgen receptor gene. AIS is an X-linked recessive disorder that is classified as complete, partial, or mild based on the phenotypic presentation. The clinical findings include a female type of external genitalia, 46-XY karyotype, absence of Mullerian structures, presence of Wolffian structures to various degree, and normal to high testosterone and gonadotropin levels. The syndrome is illustrated by a 24-year-old phenotypic female who presented with an inability to conceive, normal-appearing external genitalia, an absent uterus and ovaries, and bilateral testes at the level of the internal inguinal ring. Management includes counseling, gonadectomy to prevent primary malignancy in undescended gonad, and hormone replacement. The karyotyping of family members is advocated because of known familial tendencies.

The Effect of Voiding Position on Uroflowmetric Parameters in Healthy Young Men

ABSTRACT

INTRODUCTION: Voiding quality can theoretically be affected by voiding position. It is important to know the effect of voiding position on urometric parameters in order to obtain optimal diagnostic test results, compare data across research investigations, and make recommendations about voiding position for the management of voiding problems. This prospective study was designed to evaluate the effect of changes in voiding position on uroflowmetric findings of young, healthy men.

METHODS: The participants were 31 male volunteers who were asymptomatic of urological disorder. They had an average age of 29.2 years (range, 23-39 years). In each of standing, sitting, and squatting positions, 2 measurements were done (6 separate measurements for each case) and the mean of each pair was determined. Outcome measures were peak flow rate (Qmax), average flow rate, time to peak flow, flow time, and voided volume. A one-way ANOVA was used to compare the voiding positions; a probability value < .05 was considered statistically significant.

RESULTS: The results for the standing, sitting and squatting positions were: mean Qmax of 23.4, 24.4, and 25.8 mL/s, respectively (P = .618); mean for average flow rates of 13.4, 13.0, and 13.9 mL/s, respectively (P = .813); mean flow times of 23.9, 22.1, and 22.9 seconds, respectively (P = .822); mean time to peak flow of 7.8, 8.0, and 6.0 seconds, respectively (P = .119); and mean voided volume of 300, 275, and 290 mL, respectively (P = .631).

CONCLUSION: The present study revealed no statistically significant differences between the standing, sitting, or squatting voiding positions for any of the measured urodynamic parameters. A precise judgment about the effect of voiding position on the uroflowmetric measures of healthy young males needs more investigation using a large number of cases, preferably with heterogeneous typical voiding positions.

Primary Renal Carcinoid Tumor Presenting as an Unusual Calcific Mass

ABSTRACT

Calcification in nonrenal carcinoid tumors is common, but it is extremely rare to find calcification in renal carcinoids. Neuroendocrine cells are not found in normal renal parenchyma. We report a case of a 45-year-old male who presented with vague abdominal pain. Investigations showed that he had a calcified mass in the left kidney. We performed a nephrectomy. Histopathological tests showed that it was a carcinoid tumor. The patient was investigated further, but there was no evidence of any extrarenal primary focus of a carcinoid tumor. Whenever a carcinoid of the kidney is diagnosed, a thorough evaluation for another focus of carcinoid tumor is mandated because 54% of reported cases have metastatic lesions at initial presentation. When present, calcification is considered a stigmata of long-term tumor growth and associated with a more indolent course.

Renal Cell Carcinoma With Bone Metastasis: Case Report of a Missed Diagnosis

ABSTRACT

Renal cell carcinoma (RCC) accounts for 2% of all cancers. Although it often results in lung metastasis, bony metastases are uncommon. RCC may not be diagnosed until after it has metastasized because the primary tumor can grow fairly large without creating symptoms such as flank pain or a mass in the abdomen. We report a 38-year-old male who presented with right loin pain typical of ureteric colic. Clear cell RCC was not diagnosed until histological evaluation was completed after a nephrectomy. A bone scan showed widespread skeletal metastasis. Use of bone scans and other diagnostic tests for suspected RCC is discussed.

Primary Renal Leiomyosarcoma: A Brief Case Report

ABSTRACT

Renal leiomyosarcomas are rare tumors of the kidney, comprising 0.5% to 1.5% of all malignant renal tumors in adults. A 65-year-old male presented with generalized weakness and flank pain in the right lumbar area for the last 8 months. Radiological imaging revealed a heterogeneous mass in the right kidney, with no lymphadenopathy or venous thrombosis. The tumor measured 15 cm at its greatest axis and replaced almost the entire kidney. His metastatic work-up was negative. He underwent right radical nephrectomy. Histopathology revealed spindle-shaped sarcoma; immunohistochemistry confirmed a primary renal leiomyosarcoma. The patient is doing well 1 year after surgery.

Intrarenal Pseuodoaneurysm After Percutaneous Nephrolithotomy: A Rare and Important Complication of Minimally Invasive Surgery

ABSTRACT

A renal artery pseudoaneurysm (RAP) is created by high-pressure blood passing from a lacerated artery into the renal parenchyma. It has been reported to occur after trauma, renal biopsy, percutaneous nephrostomy, percutaneous nephrolithotomy (PCNL), and open or laparoscopic partial nephrectomy. The incidence of this rare, potentially life-threatening complication is likely to increase with the increasing popularity of endoscopic renal procedures. We present a case of a 60-year-old male who received PCNL for a calculus in the lower calyx of the left kidney. Twenty days after the PCNL, the patient was readmitted due to severe gross hematuria and clot retention. Angiography revealed a pseudoaneurysm arising from the interlobar artery of the lower pole. RAP is often difficult to diagnose and requires a high index of suspicion. We successfully performed coil angiographic embolization, which is considered the most appropriate treatment. Other treatment options are discussed.

Incidental Finding of an Appendicular Mass During Surgery In a Living Donor Kidney Recipient: A Case Report

ABSTRACT

An appendicular mass was discovered in a 44-year-old female recipient of a living donor kidney at the beginning of the transplant surgery. The donor nephrectomy was put on hold while the mass was explored. A perforated appendix was found and an appendectomy was completed with suture ligation of its stump. Because all infected tissue was eliminated, we proceeded with the kidney transplant. Immunosuppression treatment was tailored to the special circumstances. Only antithymocyte globulin was used until the patient had return of bowel function. She was discharged home on regular triple immunosuppression and doing well at the 6-month follow-up examination. The incidental discovery of an appendicular mass at the time of transplant surgery may not be an absolute contraindication to immediate kidney transplantation, if the patient meets specific selection criteria.

Early Endoscopic Management of Posttraumatic Posterior Urethral Stricture

ABSTRACT

INTRODUCTION: Some studies of primary realignment of urethral stricture show higher long-term complication rates than those observed in patients treated with delayed repair, but the results are not thoroughly documented. The purpose of this study was to evaluate the results of early endoscopic management of posttraumatic posterior urethral stricture by visual internal urethrotomy (VIU).

METHODS: Participants were 14 males with posterior urethral strictures following a car accident. All patients had partial injuries to the urethra. The strictures were 1-2 cm long. Participant mean age was 21 years (range, 18-26 years). Patients were evaluated by medical history, clinical examination, laboratory investigations, and radiological imaging. VIU was done within 2 weeks of trauma. Follow-up examinations were done at 1, 3, 6, 12, and 24 months after surgery. Outcome measures were flow rates and postoperative complications.

RESULTS: All patients were continent with satisfactory flow rates. One patient had impotence, but his condition was improved at the 6-month follow-up. Other complications included dysuria (n = 5), urinary tract infection (UTI) (n = 2), and urge incontinence associated with UTI (n = 1). After 12 months, 1 patient required surgical intervention due to a decrease in flow rate and recurrence of stricture.

CONCLUSION: Based on this report of 14 patients, early endoscopic urethral realignment surgery is a safe procedure with few complications. Endoscopic restoration of urethral continuity may be considered for early treatment of posttraumatic posterior urethral stricture.

Free Uroflow Versus Pressure-Flow Urodynamic Outcomes: Does the Transurethral Catheter Cause a Measurement Artifact?

ABSTRACT

INTRODUCTION: The effect of a transurethral catheter on urodynamic pressure-flow studies has been questioned, especially for patients with bladder outlet obstruction (BOO). The purpose of this retrospective study was to compare urodynamic outcomes measured during free uroflowmetry with pressure-flow studies using a transurethral catheter.

METHODS: We retrospectively reviewed the records of 22 adult patients who had voided volume that did not differ by more than 20% during 2 assessments: free uroflow and pressure-flow with a transurethral 5 Fr catheter in situ. The outcome measures were maximum flow (Qmax), average flow rate, voiding time, time to Qmax, and flow acceleration. Free uroflow and pressure-flow outcomes were compared using paired t tests. A Bonferroni adjustment was applied; probability < .01 was considered statistically significant.

RESULTS: There were 17 males and 5 females. The mean age was 39.9 years (range, 18-80 years). The urodynamic findings were reported as: normal (n = 6), hypocontractile detrusor (n = 5), BOO (n = 5), overactive bladder symptom complex (n = 4), and low pressure-low flow system (n = 2). Qmax was significantly higher during free uroflow than during pressure-flow recordings (P = .001). Average flow rate was also significantly higher during free uroflow (P < .001). Voiding time was significantly slower and acceleration was significantly faster during free uroflow (both with P = .001). There was no significant difference between recording conditions in the time to Qmax.

CONCLUSION: There appears to be a significant decrease in some uroflow measurements with a 5 Fr urethral catheter in situ during pressure-flow studies, which is contrary to the previous claim that any catheter smaller than 6 Fr does not alter the results. This measurement artifact needs to be considered when interpreting urodynamic studies, particularly if the patient has BOO. To compensate for differences between the free uroflow rate and uroflow rate with a catheter, the free uroflow rate and detrusor pressure may need to be considered when evaluating the degree of BOO.

Giant Hydronephrosis Due to Congenital Ureteropelvic Junction Obstruction

ABSTRACT

Giant hydronephrosis caused by congenital ureteropelvic junction obstruction is very rare, particularly now that imaging techniques are more widely available. We introduce a 16-year-old boy who presented with abdominal pain and distention. He had a cystic mass in the central and right side of the retroperitoneum that filled the space from the right subdiaphragmatic area superiorly to the pelvis inferiorly. It measured 35 cm x 23 cm x 20 cm. His pelvic capacity was 8050 mL. The parenchyma of the right kidney was not observed; the left parenchyma was normal. We performed a right thoracoabdominal nephrectomy. Early diagnosis is essential to the prevention of this disorder.

Prevalence of Acquired Renal Cystic Disease in Patients With End-Stage Renal Disease Receiving Hemodialysis

ABSTRACT

INTRODUCTION: The effect of hemodialysis on acquired cystic renal disease (ARCD) in patients with end-stage renal disease (ESRD) is not fully understood. The purpose of the study was to determine the prevalence of ARCD in patients with ESRD from our institution and to investigate the relationship between ARCD and the duration of hemodialysis.

METHODS: This prospective cross-sectional study was conducted between August 2008 and August 2009. We evaluated a total of 410 patients with ESRD; 182 patients were still undergoing hemodialysis at the end of the study period and 228 patients had hemodialysis followed by renal transplantation. Patients with autosomal dominant polycystic kidney disease were excluded. Patients had renal sonography evaluations before and during hemodialysis. Chi-square was used to compare the categorical distribution of the total number of patients with ESRD with the subset of patients with ARCD for the outcome measures of age, sex, duration of hemodialysis, and causes of ESRD.

RESULTS: A total of 34 cases were excluded due to lack of cooperation. From the remaining 376 patients, 31 (8.2%) had ARCD, 80 (21.3%) had a simple renal cyst, and the remaining 265 (70.5%) had noncystic ESRD. The mean age was 45 years (SD = 17; range, 10-85 years). The largest percentage of the total population of patients with ESRD was 20-39 years old; the largest percentage of patients with ARCD was > 60 years old (P < .001). There was no significant difference in the sex distribution of the total group and the subset of patients with ARCD. The mean duration of hemodialysis for all patients in the study was 27 months (SD = 14; range, 1 month to 17 years). Most of the total population of patients with ESRD were on dialysis for < 1 year; most patients with ARCD were on dialysis for > 5 years (P < .001). The majority of both the total number of patients and the patients with ARCD had hypertension or hypertension plus diabetes mellitus.

CONCLUSION: Patients who are on long-term hemodialysis should be monitored for the development of ARCD.

Laparoscopic Surgery in a Patient With Bilateral Adrenal Myelolipoma

ABSTRACT

Adrenal myelolipoma is a rare benign adrenal tumor composed of adipose tissue and hematopoietic elements. Myelolipomas are often asymptomatic. The preferred diagnostic imaging modality is computed tomography (CT), which shows focal fatty density within the mass. Surgical intervention is recommended if the mass is larger than 5 cm. A 52-year-old female patient was referred for chronic dull abdominal pain. CT demonstrated left side (6.5 cm x 7 cm) and right side (1 cm x 2.5 cm) well-outlined adrenal masses with a fat density in the suprarenal regions. They were hormonally nonfunctional. The patient underwent laparoscopic left adrenalectomy. The right mass was left intact because of its small size. There were no complications. Histopathological examination revealed myelolipoma. Laparoscopic adrenalectomy can be a safe and effective treatment for select cases.

Safety and Efficacy of the Ophira Mini-Sling System: One Year Follow-Up From a Multicenter International Clinical Trial

ABSTRACT

INTRODUCTION: The Ophira mini-sling system (Promedon; Cordoba, Argentina) uses a minimally invasive, midurethral low-tension tape that is anchored to the obturator internus muscles bilaterally at the level of the tendinous arc by a single vaginal incision. It minimizes surgical trauma and enables an outpatient procedure. First-year follow-up results are reported.

METHODS: The study was a prospective clinical trial conducted from February 2008 to March 2010. Participants were 149 female patients with stress urinary incontinence from Brazil and Argentina. Their mean age was 53.9 years (SD = 9.5; range, 36-71 years). All patients received a medical history, physical examination, stress test, standardized 1-hour pad test, and urodynamic study. Patients also completed the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) and Urogenital Distress Inventory (UDI-6). All underwent treatment with the Ophira mini-sling system. The procedure was conducted under local (73%), general (18%), or regional anesthesia (9%). A vertical 1 cm long vaginal incision was performed at 1 cm from the urethral meatus to deliver the prosthesis. Patients repeated the presurgical tests at 1, 3, 6, and 12 months after surgery. Outcome measures were postvoid residual volume, pad and stress test results, ICIQ-SF and UDI-6 scores, and complications. Means and standard deviations were calculated and tabled.

RESULTS: The mean (SD) operative time was 12.6 (7.4) minutes. One patient receiving the procedure under local anesthesia had severe intraoperative pain and needed intravenous sedation. Severe bleeding and technical problems with the device were not observed. The mean follow-up was 9 months; 91 patients had 12 months of follow-up evaluations. Postvoid residual volumes were variable across time. Pad tests showed less urine leakage after surgery. The percentage of patients with a positive stress test dramatically decreased after surgery. ICIQ-SF and UDI-6 scores also decreased. Major complications were not observed. Minor complications were mesh exposure (n = 3), urinary retention (n = 3), urinary tract infection (n = 8), and de novo urge incontinence (n = 7).

CONCLUSIONS: The Ophira mini-sling system appears to be an effective, minimally invasive option for the treatment of stress urinary incontinence.
