Urethral stents are frequently used for urinary diversion after hypospadias surgery. In this study, we aim to compare the results of no-balloon catheter (nelaton catheter) and modified foley catheter usage after TIPU operations in adults.

The medical records of 53 adult patients who applied TIPU for subcoronal or midpenile hypospadias between November 2008 and September 2012 were evaluated retrospectively. Patients were evaluated in two groups based on the performed urinary diversion. Group 1 was composed of 29 patients to whom 16 F nelaton catheter was used for urinary diversion between November 2008-December 2010, whereas Group 2 consisted of 24 patients to whom 12 F foley catheter coated by 16 F nelaton catheter by half was used for urinary diversion between February 2011 – September 2012.

There was no statistically significant difference between Group 1 and Group 2 in terms of age, the location of the mea, the number of secondary cases, the length of the neourethra, fistula and urethral stricture (p>0.05). Surgery success rate was 79.3% in Group 1 and 79.1% in Group 2 (p>0.05). At the 6th month follow-up, no statistically significant difference was found between two groups regarding fistula and urethral stricture. In terms of postoperative patient comfort, Group 2 were better than Group 1 (p<0.05).

Twelve F foley catheter, half of which is coated with 16 F nelaton catheter, could be used for diversion in TIPU operations in adult patients with distal and mid-shaft penile hypospadias to reduce postoperative patient discomfort.
