Abstract

OBJECTIVE:

The aim of this study is to evaluate the effects of the different immediate treatment modalities on the sexual and voiding functions in pelvic fracture urethral injuries.

METHODS:

The records of 38 male patients with traumatic posterior urethral injuries were reviewed, 18 of whom were treated by initial suprapubic cystostomy and delayed repair (Group 1), and 20 by primary urethral realignment (Group 2). Types of pelvic fractures and urethral injuries were classified according to surgical and radiological findings. Long-term voiding functions were determined by the patient questionnaire, residual urine and uroflow. Sexual functions were also determined by the patient questionnaire and a penile duplex ultrasound study.

RESULTS:

Mean follow-ups of Groups 1 and 2 were 37 and 39 months, respectively. Membranous urethral disruption extending to the urogenital diaphragm was the most frequent urethral injury (type 3), with incidences of 66.7% and 77.7%, respectively. There were no statistically significant differences in mean age, incidence of pelvic fracture types and urethral injury types between groups (p > 0.05). After the immediate treatments, 16.7% and 55% of the patients regained normal urination, and stricture developed in 83.3% and 45% of the patients, respectively. In 44.4% of the patients in Group 1 and 10% in Group 2, urethral strictures required open urethroplasty (p < 0.05). Erectile impotence before urethroplasty in 17.6% and 20%, anejaculation after urethroplasty in 17.6% and 15% and incontinence in 5.6% and 10% of the patients were found in Groups 1 and 2, respectively (p > 0.05). However, 88.8% and 90% of patients eventually achieved normal urination with complete continence.

CONCLUSION:

Sexual and voiding dysfunction after pelvic fracture posterior urethral injury seem to be the result of the injury itself, not of the immediate treatment modalities. In urethral disruption injuries, primary urethral realignment seems more favourable than suprapubic cystostomy and delayed repair.
