Complications rates of non-oncologic urologic procedures in population-based data: a comparison to published series

PUSPOSE: Published single institutional case series are often performed by one or more surgeons with considerable expertise in specific procedures. The reported incidence of complications in these series may not accurately reflect community-based practice. We sought to compare complication and mortality rates following urologic procedures derived from population-based data to those of published single-institutional case series. MATERIALS AND METHODS: In-hospital mortality and complications of common urologic procedures (percutaneous nephrostomy, ureteropelvic junction obstruction repair, ureteroneocystostomy, urethral repair, artificial urethral sphincter implantation, urethral suspension, transurethral resection of the prostate, and penile prosthesis implantation) reported in the U.S.’s National Inpatient Sample of the Healthcare Cost and Utilization Project were identified. Rates were then compared to those of published single-institution series using statistical analysis. RESULTS: For 7 of the 8 procedures examined, there was no significant difference in rates of complication or mortality between published studies and our population-based data. However, for percutaneous nephrostomy, two published single-center series had significantly lower mortality rates (p < 0.001). The overall rate of complications in the population-based data was higher than published single or select multi-institutional data for percutaneous nephrostomy performed for urinary obstruction (p < 0.001). CONCLUSIONS: If one assumes that administrative data does not suffer from under reporting of complications then for some common urological procedures, complication rates between population-based data and published case series seem comparable. Endorsement of mandatory collection of clinical outcomes is likely the best way to appropriately counsel patients about the risks of these common urologic procedures.

Complications following urethral reconstructive surgery: a six year experience

PURPOSE: We present a single institutional experience over 6 years of intra and postoperative complications following urethral reconstructive surgery, and the impact of these complications on overall results. MATERIALS AND METHODS: From June 2000 through May 2006, 153 consecutive urethral reconstructive procedures were performed on 128 patients by one surgeon (CMG). Complication rates were determined, and subgroups were categorized based on stricture etiology, patient age, length of stricture, location of stricture, type of repair, and presence of various co-morbid conditions. RESULTS: Overall, 23 of 153 cases (15 percent) had an intra or postoperative complication with a mean follow-up time of 28.3 months (range 3 to 74). The most common complications were related to infection (n = 9). Other complications included repair breakdown (n = 4), bleeding (n = 4), fistulae (n = 3), thromboembolic (n = 2), positioning-related (n = 2), and Foley catheter malfunction (n = 1). Complication rates for anastomotic and substitution urethroplasty were 9.1 percent (4/44) and 17 percent (19/109), respectively. The number of patients with at least one year of follow-up who had a complication and eventual stricture recurrence was 20 percent (4/20), while only 7.4 percent (7/95) of those who did not have a complication recurred (p = 0.08). CONCLUSIONS: Complications following reconstructive surgery for urethral stricture disease were mostly related to infection or repair breakdown in the immediate postoperative period. It does not appear that an intra or postoperative complication following urethral reconstructive surgery impacts the chance of eventual stricture recurrence at intermediate follow-up.

Full-thickness abdominal skin graft for long-segment urethral stricture reconstruction

Multiple tissue sources have been used for urethral reconstruction in adults. Patients with lichen sclerosis (LS), long segment strictures, or prior oral graft use have less available tissue for urethroplasty. We describe a technique for the use of a full-thickness skin graft of hairless abdominal skin for long segment urethroplasty.

Mannitol extravasation during partial nephrectomy leading to forearm compartment syndrome

We present the first known complication of forearm compartment syndrome after mannitol infusion during partial nephrectomy. We stress the importance of excellent intravenous catheter access and constant visual monitoring of the intravenous catheter site during and after mannitol infusion as ways to prevent this complication. Prompt recognition of compartment syndrome with appropriate intervention can prevent long-term sequelae.
