The natural history of renal functional decline in patients undergoing surveillance in the DISSRM registry.

Objective: To describe the natural history of renal function in patients on active surveillance (AS) for small renal masses (SRM) in the Delayed Intervention and Surveillance for Small Renal Masses Registry.

Methods: Delayed Intervention and Surveillance for Small Renal Masses is a prospective, multi-institutional registry of patients with SRM (≤ 4 cm) who choose intervention or AS. Of these, 64 patients on AS had longitudinal serum creatinine (sCr) values and underwent analysis of estimated glomerular filtration rate (eGFR).

Endoscopic management of intraluminal ureteral endometriosis.

Objective: To present the largest experience on the ureteroscopic management of ureteral obstruction secondary to intraluminal endometrial implantation.

Materials And Methods: We retrospectively evaluated patients who underwent ureteroscopic management of intraluminal endometriosis from 1996 to 2012. All patients were diagnosed with ureteroscopic biopsy and underwent at least 1 ureteroscopic ablation with a holmium YAG (Ho:Yag) laser.
