Summary: | Orthotopic reconstruction following cystectomy has evolved in an attempt to restore anatomy and function to as close as possible to the preoperative state. We review the renal and functional outcomes of patients who underwent cystectomy and neobladder reconstruction at our institution.
Between December 2003 and October 2007, 31 patients underwent cystectomy with Studer neobladder reconstruction at the Ottawa Hospital, Ottawa, Ontario, Canada. Follow-up data were obtained regarding renal function (serum creatinine, μmol/L), continence, urinary flow rates and post-void residual (PVR) at 3, 6 and 12 months after surgery. Change in creatinine from preoperative baseline was calculated and analyzed by student t-test to determine if there was a significant rise in creatinine.
There was a statistically significant increase in creatinine from preoperative baseline, with an average increase of 17.3 μmol/L, 21.8 μmol/L and 26.3 μmol/L at 3, 6 and 12 months, respectively. Six patients developed hydronephrosis. Excluding patients with hydronephrosis, there continued to be a statistically significant rise in creatinine with an average increase of 11.9 μmol/L, 14.7 μmol/L and 19.4 μmol/L at 3, 6 and 12 months, respectively. At 1 year, daytime continence was achieved by 89% of patients; 70% were continent at night.
Orthotopic neobladders have excellent functional outcomes with low rates of incontinence, which improved throughout follow-up. A significant proportion of patients developed hydronephrosis, highlighting the need for close follow-up to prevent reversible renal deterioration. Creatinine increased during follow-up irrespective of the development of hydronephrosis, but the clinical significance is unknown. |
