Subcutaneous nephrovesical bypass: Treatment for ureteral obstruction in advanced metastatic disease.

The aim of the present study was to explore the value of subcutaneous nephrovesical bypass (SNVB) for the treatment of ureteral obstruction due to pelvic metastatic disease. SNVB stents (n=30) were implanted in 24 patients with advanced metastatic disease between January 2008 and December 2012. Urinalysis, serum creatinine (SCr), glomerular filtration rate (GFR), quality of life (QoL) scores, and renal ultrasonography were evaluated at follow-up.

Comparative analysis of upper ureteral stones (> 15 mm) treated with retroperitoneoscopic ureterolithotomy and ureteroscopic pneumatic lithotripsy.

Objective: To investigate an appropriate treatment for patients with upper ureteral stones, > 15 mm in size, by comparing the therapeutic outcomes for those undergoing retroperitoneoscopic ureterolithotomy (RPUL) and rigid ureteroscopic pneumatic lithotripsy (URSPL) retrospectively.

Patients And Methods: During the study period, 81 patients with a large upper ureteral stone (> 15 mm) were divided into two groups. RPUL was performed with retroperitoneal approach, and the stone was removed in group A.
