ABSTRACT
OBJECTIVE:
To collate available data via systematic review considering etiology, presentation, and treatment of Uro-Symphyseal Fistula (USF) in order to inform a contemporary management framework. MATERIALS ANDMETHODS:
A systematic review was performed according to the Cochrane Handbook and registered in PROSPERO (CRD42021232954). MEDLINE and CENTRAL databases were searched for manuscripts considering USF published between 2000 and 2022. Full text manuscripts were reviewed for clinical data. Univariate statistical analysis was performed where possible.RESULTS:
A total of 31 manuscripts, comprising 248 USF cases, met inclusion criteria. Suprapubic pain and difficulty ambulating were common symptoms. MRI confirmed the diagnosis in 95% of cases. Radiotherapy for prostate cancer was the most common predisposing factor (93%). Among these patients, prior endoscopic bladder outlet surgery was common (83%; bladder neck incision/urethral dilatation n = 59, TURP/GLL PVP n = 34). In those with prior prostatic radiation, conservative management failed in 96% of cases. Cystectomy with urinary diversion (86% n = 184) was favored over bladder-sparing techniques (14% (n = 30) after prior radiation. In radiation naïve patients, conservative management failed in 72% of patients, resulting in either open fistula repair with flap (62%) or radical prostatectomy (28%).CONCLUSION:
Prior radiotherapy is a significant risk factor for USF and almost always requires definitive major surgery (debridement, cystectomy, and urinary diversion). On the basis of the findings within this systematic review, we present management principles that may assist clinicians with these complex cases. Further research into pathogenesis, prevention, and optimal treatment approach is required.
