Anastomotic stricture (AS) is a well-described complication of radical retropubic prostatectomy (RRP) despite all the refinements in surgical technique. We aimed to define and discuss the role of postoperative urinary drainage on AS development.

A total of 136 patients with localized prostate carcinoma underwent RRP. In all patients, urethral catheter was removed 3 weeks after RRP without a cystogram. We documented duration of drainage (<3 days, n = 86; 3-5 days, n = 36; and >5 days, n = 14), volume of drainage (<300 ml, n = 78; 300-500 ml, n = 27; and >500 ml, n = 31), and mean volume of drainage per day (<100 ml, n = 85 and >100 ml, n = 51), continence status, and clinical and histopathological characteristics of patients as risk factors related with AS

AS was diagnosed in 28.6% of patients. The rate was found to be 35.9%, 41%, and 23.1%, consistent with duration, and 38.4%, 15.4%, and 46.2% according to volume of drainage, respectively (P = 0.0001). AS occurred in 43.6% and 56.4% of patients concerning mean volume of drainage per day, respectively (P = 0.007). Analysis showed that AS was significantly associated with duration (>3 days), total volume (>500 ml), and the mean volume (>100 ml) of urinary drainage among the variables. The rates of urinary incontinence were 30.7% in patients with AS and 6.2% in patients without AS

Time and the amount of urinary drainage were significantly associated with stricture formation following RRP that might be caused by partial disruption of the anastomosis.
