How we made exstrophy bladder continent and preserved the renal functions

Abstract

Purpose: Crucial requirement of exstrophy bladder repair is to make patients continent as well as to preserve kidney functions. We analyzed our patients' data retrospectively to study their continence and to find out the justification behind continence and preservation of renal functions. Patients and Methods: We selected files of 18 fully continent patients from 52 patients operated. Eleven out of 18 patients were presented from beginning and 7 were referred after around 8 to 14 years, as incontinent bladder following good repair of bladder neck and posterior urethra. Eleven were operated with complete primary repair of exstrophy along with pubic osteotomy minimal and were kept on cystostomy track (CT) till augmentation to vent out vesical pressure. In seven patients, we did reduction of caliber of posterior urethra and bladder neck along with CT followed by augmentation after 6 months. Results: All 18 patients are maintaining dry period for 24 h. Two patients had enuresis but are manageable with partial fluid restriction from evening. Seventeen out of 18 patients are maintaining their renal functions. Conclusion: No tension abdominal wall closure with rectus muscle apposition is essential to preserve repaired bladder exstrophy. Osteotomy prevents lateral drag to overcome failure of whole reconstruction. Increased “systolic” vesical pressure from contraction of small bladder might destroy the mechanism of continence and renal functions. Hence, venting of vesical pressure through CT is obligatory till augmentation which is of necessity to be done as early as possible to create a low-pressure continent system.
