Abstract
Surgery on lower urinary tract organs sometimes is hindered by the symphysis pubis, which by its position and bulk could severely restrict maneuverability. Since 1972 we used a transpubic approach to improve surgical exposure in 287 patients operated on for prostate, bladder or urethral cancer, post-traumatic strictures and other conditions. The type of pubectomy performed (total, partial superior or partial inferior) depended upon whether a suprapelvic or infrapelvic diaphragm organ was the primary target of the approach. Total pubectomy was used in 137 patients, partial superior bone resection in 140 and partial inferior resection in 10 patients. Technical details for each type of pubectomy are illustrated. The transpubic approach was particularly useful for repair of posterior urethral strictures or removal of bulky tumors. Among the 3 types of approaches used, total pubectomy was associated with a high complication rate including bleeding, pelvic instability, urinary incontinence and stricture of the vesicourethral anastomosis. Therefore, we have abandoned the technique since 1978. Partial pubectomy provides exposure comparable to that of total pubectomy but with minimal complications, making it an alternative to the standard approach in difficult cases.
