Light-guided renal cyst fenestration during laparoscopic ureterocalicostomy in a patient with left ureteropelvic junction obstruction.

Introduction: Laparoscopic ureterocalicostomy is a useful alternative to laparoscopic pyeloplasty for treating ureteropelvic junction obstruction under certain conditions. One concern regarding this technique is the inevitability of amputation of the renal lower pole to expose the lower renal calyx.

Case Presentation: A 43-year-old man who presented ureteropelvic junction obstruction and multiple renal cysts underwent laparoscopic pyeloplasty, which could not be performed because of the intrarenal ureteropelvic junction.

Usefulness of urinary NMP22 to detect tumor recurrence of superficial bladder cancer after transurethral resection.

Background: In a prospective study we compared the usefulness of urinary nuclear matrix protein 22 (NMP22) with that of urine cytology and other urinary markers in the monitoring of superficial bladder cancer after transurethral resection (TURBT).

Methods: The subjects were 156 patients, comprising 99 patients with superficial bladder cancer in whom TURBT was planned (untreated group) and 57 patients without tumors in the bladder who had been followed up after TURBT (follow-up group).

Results: Among the 156 patients, who were monitored for 11-26 months (median, 21 months), recurrence was observed in 51 patients (33.
