Objectives:
To determine if low-risk patients can be identified in whom cystography is unnecessary to assess the integrity of the vesico-urethral anastomosis after radical retropubic prostatectomy (RRP), and thus who can have early catheter removal.
Patients And Methods:
In all, 275 RRPs by one surgeon were analysed retrospectively; the surgical technique, blood loss and comorbidity were recorded. Cystograms were taken 8 days after RRP to assess vesico-urethral integrity before catheter removal.
Results:
Of the 275 patients, 75% and 89% had cystography before 8 and 10 days after RRP, respectively; 71% of patients had no leak on cystography and were catheter-free at 8 days. Eighty-four leaks were identified, of which 25 (9.6%) were moderate or large. Previous transurethral prostatectomy, ischaemic heart disease, blood loss, mucosal eversion and preservation of the prostatic urethra were significant risk factors for developing a leak and were used to create a nomogram to assess the relative risk of leakage. However, none of the variables assessed, either alone or combined, could be used to predict which leaks were clinically significant.
Conclusions:
Leakage cannot be reliably predicted at the vesico-urethral anastomosis. Cystograms are necessary to identify clinically significant leaks at 8 days and should be taken if early catheter removal is being considered.
