    Abstract:
    BACKGROUND: Urologic cases constitute about 25% of a busy surgical practice in Nigeria with up to 50% of these cases being genito-urinary abnormalities in adults and children. As most urologic surgery in Nigeria is done by general surgeons, a knowledge of the disease pattern and effective techniques in management would be helpful in surgical training. OBJECTIVE: To describe the disease pattern and surgical outcomes in patients undergoing genito-urinary reconstruction in southern Nigeria METHODS: We retrospectively reviewed the medical records of patients who underwent genito-urinary reconstructive procedures by two urologists and one paediatric surgeon over a 7-year (1991-1998) period at two tertiary referral centres in southern Nigeria. We extracted data such as age, sex, nature of pathology, surgical therapy and outcomes. Patients with a follow up of 12 months were excluded. The pattern of genito-urinary disease, type and outcome of surgical therapy, and complications were determined. RESULTS: Two hundred and twenty seven patients (121 men, 39 women, and 67 children) underwent genito-urinary reconstruction during the seven years spanning 1991-1998. The study population consisted of 160 adults and 67 children (< 15 years old). Mean patient age was 43 years with a range of 18-87 years for adults and three years (range 18 months-13 years) for children. Mean follow up duration was 15 months, (range--13 months-seven years). Urethral abnormalities comprised 69% (98/ 227) of the lesions. The most common abnormality was urethral stricture in 98 (43%) patients. Urethral strictures were reconstructed as follows; primary anastomosis 83 (84.6%), pedicled penile skin island 6 (6.1%), Blandy 2 stage, 4 (4%), meatoplasty three (3%) and meatotomy, two (2%). The overall complication rate for repair of urethral strictures was 4.08%. There were 79 (35%) congenital lesions, including hypospadias 62 (27%), pelvi-ureteric junction obstruction 13 (6%), bladder exstrophy 2 (0.8%), chordee without hypospadias, 2 (0.9%), and concealed penis 1 (0.4%). These were managed using the following techniques; MAGPI, 30 (48.3%), urethroplasty, 22 (10%) single stage 10 (45%), two-stage 12 (55%), and urethral mobilization 10 (16%). Vesico-vaginal fistula complicating obstructed labour and pelvic surgery was the main cause of urinary fistulae. Ten patients underwent microsurgical epididymo-vasostomy for obstructive azoospermia resulting in three pregnancies. CONCLUSION: Lower urinary tract reconstruction represents a major proportion of urologic surgery in southern Nigeria. Management by urologic specialists results in good outcomes, therefore urologic training in this area should include a large component of lower urinary tract reconstruction.
