Randomized Controlled Trial Multicenter Study Comparative Study
A prospective randomized multicenter study of Turkish Society of Urooncology comparing two different mechanical bowel preparation methods for radical cystectomy.
To investigate the outcomes and complication rates of urinary diversion using mechanical bowel preparation (BP) with 3 day conventional and limited BP method through a standard perioperative care plan. ⋯ Regarding all endpoints, including septic and nonseptic complications, current clinical research offers no evidence to show any advantage of 3-day BP over limited BP.

Renal dysfunction is common in urologic patients, especially in those undergoing nephrectomy for renal cancer. Partial nephrectomy better preserves renal function than radical nephrectomy, but is associated with acute kidney injury related to loss of nephrons and ischemic injury. ⋯ Molecular markers, such as cystatin C, neutrophil gelatinase-associated lipocalin (NGAL), IL-18 and kidney injury molecule-1 (KIM-1), better quantify the extent of acute ischemic and/or tubular injury than other currently available tools. The use of these and/or other markers may facilitate research to improve outcomes following partial nephrectomy.

To define characteristics of the first cycle of intermittent androgen deprivation (IAD) that would predict for outcomes in a long term follow-up. ⋯ Cases with BP after RP selected to IAD that show at the first cycle a PSA nadir ≤ 0.1 ng/ml and a off-phase interval ≥ 48 weeks may identify candidates who will experience better response to IAD treatments and delayed CP or CRPC development.

Late relapses (>2 years) after completion of chemotherapy are rare and often platinum-resistant. There are limited data concerning late relapses in chemotherapy-naïve patients with stage I germ cell tumors. This retrospective analysis was performed to compare the outcome between patients with stage I germ cell tumors, who had late (≥2 years) and early (≥3 months and <2 years) relapse after orchiectomy. ⋯ Late relapses following stage I germ cell tumors were associated with seminoma, older age, and worse outcome after induction chemotherapy.
