Background
Prostate Cancer (PCA) is the most common malignancy in men >50 years of age, with radical resection being the primary treatment modality for localized PCA, with a post-operative 10-year cancer-specific survival of up to 99%. PCA radical surgery requires anastomosis of the bladder urethra to reestablish urethral continuity, with intraurethral catheter retention for 2-3 weeks as a routine procedure with the aim of: 1. draining urine before healing of the anastomotic stoma, reducing urine leakage, hematocele leakage and inflammation of the anastomotic stoma, 2 supporting the anastomotic stoma to promote healing of the urethra, 3 preventing urethral stricture of the anastomotic stoma, 4 and flushing the bladder.
However, as the whole prostate is removed when PCA is radically cured, the original morphological structure is lost to a certain extent, the proximal bladder neck and the distal urethra are both rebuilt, the bladder-urethra anastomotic orifice is naturally closed, the ureteral opening in the proximal triangular region is pressed by the ureteral balloon to be closer to the anastomotic orifice, in addition, secretions or inflammation can occur in the healing process of the anastomotic orifice, the conventional ureter only has drainage holes at the tip of the balloon, and urine, hematocele, effusion or secretion is not drained thoroughly and remains after a considerable part of cases occur. The literature reports that the incidence rate of anastomotic leakage is up to 33%, which finally causes the accumulation of liquid at the anastomotic opening, the overflow leakage from the anastomotic opening to the pelvic cavity, the secondary inflammation of urinary tract and pelvic operation area, the occurrence of urinary fistula and anastomotic stenosis, and the influence on the urinary control function of a patient after the operation.
