Introduction A variety of pathologic conditions may result in ureteral stricture disease. These include urolithiasis, genitourinary infection, retroperitoneal fibrosis, radiation therapy, external trauma, and iatrogenic injury. Strictures below the pelvic…
Indications With the use of shockwave lithotripsy (SWL) and advances in endoscopic technology and instrumentation, open surgery, once the mainstay treatment of ureteral stones, is now uncommon. Laparoscopic or robotic-assisted…
Indications and contraindications Ureteral reimplantation is utilized in cases of ureteral obstruction of the distal ureter. Ureteral obstruction may be due to inflammatory, infectious, iatrogenic, or traumatic causes, as well…
Introduction The incidence of renal cell carcinoma (RCC) has increased by 1.5% per year over the last decade and remains a primarily surgical disease. Nephron-sparing surgery for RCC was developed…
Introduction The first laparoscopic pyeloplasty was performed in 1993. A subsequent series of the first 100 cases by the same surgeon demonstrated a success rate of 96%, which is comparable…
Indications and contraindications Renal cystic disease is common, with an increasing prevalence likely related to the use of cross-sectional imaging over the last several decades. Renal cysts have been identified…
Renal biopsy is a crucial tool in the diagnosis of medical disease of the kidney. Histologic information is pivotal in making treatment decisions and providing prognostic information. Ultrasound-guided percutaneous needle…
Introduction Ureterolysis is performed to relieve ureteral obstruction caused by extrinsic compression. Obstructive encasement of the ureter is most often secondary to prior retroperitoneal insults resulting in a desmoplastic reaction….
Introduction Due to the increased use of cross-sectional imaging coupled with advances in imaging technologies, the incidence of renal tumors, particularly small renal masses (SRM), has increased significantly. , Historically,…
Urothelial carcinoma can arise from any part of the urothelium: bladder, renal collecting system, or ureter. The nomenclature of upper tract urothelial carcinoma (UTUC) is reserved for tumors that are…
