To assess the efficacy and morbidity of percutaneous nephrolithotomy (PNLT) in the treatment of renal stones in patients with neurogenic lower urinary tract dysfunction (NLUTD).

Retrospective, monocentric study including all patients with NLUTD who had undergone PNLT between 2005 and 2017.

Renal stone disease is a common disorder of the urinary tract and also a significant problem because of incidence, recurrence, and severe consequences. The complex pathogenetic mechanisms of renal stone formation involve both biologic and environmental risk factors.

Urinary proteomics is a promising tool for biomarker investigation, particularly in complex kidney diseases. Fabris and colleagues report that urinary laminin subunit alpha-2 is a potential diagnostic marker of medullary sponge kidney (MSK) disease by using a label-free quantitative proteomics platform and a clinically compatible enzyme-linked immunosorbent assay.

Calculous pyonephrosis is a disease characterized by infectious hydronephrosis associated with pyogenic destruction of the renal parenchyma, with complete or almost complete loss of renal function.

The clinical data of laparoscopic nephrolithotomy performed at Peking University People's Hospital from May 2017 to June 2020 were analyzed retrospectively.

Colocutaneous fistula with nephrocutaneous fistula is a rare condition. Renal replacement lipomatosis is the result of the atrophy and destruction of renal parenchyma. We report a 60-year-old male with intermittent drainage mucus and fluid from ulcer of his right lumbar region.

Staghorn calculi are complex renal stones that occupy the majority of the renal collecting system. These stones are associated with high morbidity and can lead to recurrent urinary tract infections, urosepsis, renal deterioration, and death if left untreated.

With the increasing of the prevalence of pediatric urolithiasis (1-5%), retrograde intrarenal surgery (RIRS) is emerging as preferred option for the management of stones in pediatric patients. Although the principles of RIRS developed in adults can be applied in children, also expert adult endourologists feel uncomfortable to approach young patients due to long learning curve that usually is expected to be required in this particular setting.

Reignited by innovations in scanner engineering and software design, dual-energy computed tomography (CT) has come back into the clinical radiology arena in the last decade. Possibilities for noninvasive in vivo characterization of genitourinary disease, especially for renal stones and renal masses, have become the pinnacle offerings of dual-energy CT for body imaging in clinical practice.

Parathyroidectomy (PTX) is routinely performed in hypercalciuric renal stone patients with primary hyperparathyroidism (PHPT). However, some data indicate a persistent stone activity following PTX, raising the issue of the link between PHPT and stone disease.

To compare the hydrocoated silicone stent (Coloplast Imajin® hydro) to PercuflexTM Plus stent (Boston Scientific) in terms of patient comfort and quality of life after flexible ureteroscopy (fURS) for stone disease over a 5-week prospective follow-up.

Several energy sources are available to clear stones during PCNL. Required improvements are faster stone clearance, optimized suction and ease of use while maintaining high patient safety standard. EMS LithoClast® Trilogy, is the first device combining electromagnetic impactor with ultrasonic energy and suction, all-in-one probe.

Patients with diabetes have an increased risk for urolithiasis, but the associated risk factors remain an active area of research. We investigated whether frailty influenced the probability of patients with diabetes developing urolithiasis.

The incidence of kidney stones in the United States is currently unknown. Here, we assessed the incidence of kidney stones using recent, nationally representative data.

We used the National Health and Nutrition Examination Survey (NHANES), from 2015 to 2018.

Calyceal diverticula are rare outpouchings of the upper collecting system lying within the renal parenchyma. These often contain stones, however, carcinoma within a calyceal diverticulum is uncommon.

Metabolic syndrome (MS) individuals have a higher risk of developing chronic kidney disease through unclear pathogenic mechanisms. MS has been also related with higher nephrolithiasis prevalence. To establish the influence of MS on renal function, we designed a murine model of combined metabolic syndrome and hyperoxaluria.

The risk of developing atherosclerotic cardiovascular disease (ASCVD) is unknown for subjects with both gallstones and renal stones, nor is it known whether there is a difference in the risk between gallstones and renal stones.

Renal stones are common, with a lifetime prevalence of 10% in adults. Global incidence is increasing due to increases in obesity and diabetes, with these patient populations being more likely to suffer renal stone disease.

To characterize current practice patterns of urologists in the management of intravenous (IV) contrast allergy in the setting of endourologic procedures.

A survey was administered to all members of the Endourological Society to assess management of IV contrast allergy prior to ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL).

OBJECTIVE - To study kidney injury molecule-1 (KIM-1) biomarker levels, indicating renal tubular damage, in patients with kidney stones and in those who underwent minimally invasive method stone treatment.

PATIENTS AND METHODS - Sixty patients with renal stones between 10 and 20 mm were included into the present study.

Ankylosing spondylitis (AS) affects sacroiliac and axial joints as well as extraarticular organs, such as the eye, lung, bowel, and heart. Although examples of renal involvement in AS, such as IgA nephropathy, amyloidosis, and glomerulonephritis, have been reported, it has not been emphasized that urolithiasis is frequently formed in the clinical course of AS.
