The importance of accurate assessment and conservative management of the open bladder neck in patients with post-pelvic fracture membranous urethral distraction defects.

OBJECTIVE: To review the pre-operative assessment of bladder neck competence and assess the success of non-operative management of the bladder neck in patients with pelvic fracture membranous urethral distraction defects. PATIENTS AND METHODS: A series of four patients with long-standing post-pelvic fracture urethral distraction defects and open bladder necks demonstrated on pre-operative investigation are presented. RESULTS: All four patients were managed by perineal urethroplasty without surgery to the bladder neck. All patients were continent post-operatively despite the injury having ablated the distal sphincter mechanism. CONCLUSION: We believe that the majority of patients can be managed successfully by a non-operative approach to the bladder neck, sparing them the unnecessary operative morbidity of an abdomino-perineal repair, which should be reserved for those with obviously scarred or distorted bladder necks.

Idiopathic reduced bladder storage versus interstitial cystitis.

Idiopathic reduced bladder storage is a term we used to describe a group of patients who have subjective and objective evidence (by cystometrogram) of diminished bladder capacity without a demonstrable cause. We performed a prospective study comparing this condition with interstitial cystitis. We studied the clinical, urodynamic and histological features, and response to therapy in these 2 groups of patients. No statistical difference was found between the incidence of irritative bladder symptoms and/or suprapubic pain. Only minor differences were noted in the maximum cystometric capacity and incidence of bladder instability. Histological and immunofluorescent features were analogous. Also, the reduced bladder storage and interstitial cystitis patients responded similarly to bladder dilation and pharmacological therapy. Augmentation ileocystoplasty used in patients refractory to medical treatment produced comparable results in the short term. Based upon similar findings, it is likely that these 2 conditions represent the same disease entity with the only difference being the cystoscopic findings.
