Impact of pelvic osteotomy on the incidence of inguinal hernias in classic bladder exstrophy

Background/purpose

The high prevalence of inguinal hernias in the bladder exstrophy population is well documented. The authors' aim is to determine whether pelvic osteotomy reduces the incidence of primary and recurrent inguinal hernias in patients with classic bladder exstrophy.

Methods

Using an institutionally-approved database, patients who underwent immediate or delayed primary bladder closure between 1974 and 2012 were identified and stratified by the use of pelvic osteotomy at the time of closure. Data were analyzed using Fisher's exact test and multivariate logistic regression analysis.

Results

One hundred thirty-six patients were identified with a median follow up of 8 years. The incidence of inguinal hernias following closure was 25% in the osteotomy group versus 46% in the non-osteotomy group (p = 0.017). Osteotomy was associated with a significant decrease in recurrence of inguinal hernias amongst patients who underwent previous repair (17% versus 47%, osteotomy versus non-osteotomy, p = 0.027) and the development of primary inguinal hernias in whom initial groin exploration was negative (20% versus 39%, p = 0.029). Osteotomy and female sex were associated with a decreased rate of inguinal hernia development after bladder closure while age at closure was not.

Conclusions

Pelvic osteotomy at the time of exstrophy closure decreases the likelihood of primary or recurrent inguinal hernia development.

Management of the Recurrent Male Urethral Stricture

Urethral stricture disease negatively impacts quality of life and leads to significant urologic pathology including lower urinary tract symptoms, recurrent urinary tract infections, and potentially more severe sequelae such as detrusor dysfunction, renal failure, urethral carcinoma, and Fournier’s gangrene. Open urethral reconstruction is considered a durable and definitive treatment for urethral stricture with lifetime success rates ranging from 75–100 %; however, strictures do recur up to 10 years after surgery. Recurrence rates vary by repair type. There also is no agreed-upon modality for recurrence surveillance, but there are many modalities with varying degrees of invasiveness. Recurrent strictures may be managed endoscopically or via open repair. We review stricture recurrence rates, surveillance modalities, risk factors, and management options.     

Elimination of preoperative mechanical bowel preparation in patients undergoing cystectomy and urinary diversion

IntroductionThe utility of a preoperative mechanical bowel preparation prior to bowel surgery has recently been questioned. The purpose of this study is to compare the perioperative outcomes between patients undergoing cystectomy with urinary diversion with or without preoperative mechanical bowel preparation.MethodsSeventy patients underwent radical cystectomy and urinary diversion between May 2008 and August 2009 for bladder cancer. The first cohort of patients (n = 37) underwent cystectomy and diversion during the period May 2008–December 2008 and underwent a preoperative mechanical bowel preparation including a clear liquid diet, magnesium citrate solution, and an enema before surgery. The second cohort of patients underwent surgery during the period of January 2009–August 2009 (n=33). These patients were given a regular diet before surgery and did not undergo a mechanical bowel preparation except for the enema before surgery was performed to decrease rectal/colonic distention. Outcome measures included gastrointestinal and overall complications, and perioperative outcomes including recovery of bowel function.ResultsThere were no differences with regard to recovery of bowel function, time to discharge, or overall complication rates between the 2 groups. More specifically, the rate of GI complications was not different in prepped patients vs. nonprepped patients (22% vs. 15%; P = 0.494). There were no occurrences of bowel anastomotic leak, fistula, abscess, peritonitis, or surgical site infection in either group. One perioperative death occurred in the nonprepped group secondary to cardiovascular complications.ConclusionsPreoperative mechanical bowel preparation prior to radical cystectomy with urinary diversion does not demonstrate any significant advantage in perioperative outcomes, including gastrointestinal complications. Further studies aimed at measuring patient satisfaction and larger randomized trials will be beneficial in evaluating the role of mechanical bowel preparation prior to urinary diversion.
