Comparison of factors affecting the short-term presentation of results in the surgery of distal hypospadias in adults

Introduction To determine the factors affecting the success of distal hypospadias repair in adults. Material and methods Medical records of adult patients who underwent distal hypospadias repair in our clinic were reviewed. Patient's age, external urethral meatus location, hypospadias status, anesthesia type, diversion type, nelaton diameter and surgeons were recorded as factors affecting surgery success. Only patients, operated with tubularisation incised plate urethroplasty (TIPU) technique, were included. Results were classified as successful, stricture, fistula and slough. We compared the factors affecting the success. SPSS 16.0 were used for statistical assessment and logistic regression analysis was used to determine success. p < 0.05 was considered to show statistical significance. Results One hundred and eight patients underwent distal hypospadias repair in our clinic. Mean age was 21.44 ± 2.0. 38 patients had distal penile, 67 patients had subcoronal, 2 patients had coronal and 1 patient had glandular hypospadias. Eighty eight patients had primary, 12 secondary, 5 tertiary and 3 cripple hypospadias. Seventy eight patients underwent TIPU under local anesthesia, and 30 patients underwent under spinal anesthesia. Suprapubic catheter was used in 92 patients and transurethral catheter was used in 16 patients. Sixteen different surgeons performed the operations. Seventy operations were successful. Three stricture, 24 fistula, and 11 slough were determined. Overall success rate was 64.81%. Patient's age, external urethral meatus location, anesthesia type, diversion type, nelaton diameter and the surgeon difference did not affected surgical outcomes. Only hypospadias status (primary/redo) affected the success (p = 0.037). Conclusion The only factor affecting surgical outcomes of distal hypospadias repair in adults seems to be hypospadias status. It might be due to the lack of second layer in the redo operations.
