Preputial Graft Ureteroplasty for the Treatment of Complex Ureteral Stricture: A New Surgical Technique and Review of Literature.

Objectives

To present our first experience and 12-month outcomes of the novel technique of onlay preputial graft ureteroplasty (PGU) for complex ureteral stricture.

Methods

In December 2016, open onlay PGU was made on a male patient who have proximal stricture of the right ureter. The length of upper ureteral stricture was 50 mm. A 60 mm in length and 15 mm in width preputial graft was harvested from the ventral side of the penis and placed in the ureter as a ventral onlay for ureteroplasty. Operative time, intraoperative, and postoperative complications were recorded properly. Follow-up was performed via clinical assessment of symptoms, renal ultrasound, MR urography, and nuclear scan renography.

Results

The new technique was effectively performed without any intraoperative and postoperative complications. Residual hydronephrosis in the right side was found through ultrasonography 3, 6, and 12 months and MR urography 6 months postoperatively. But complaint of the patient's pain passed completely.

Conclusions

Within our knowledge, we present the first experience with onlay PGU for proximal ureteral stricture. Twelve-month results indicate that the new technique appears to be an excellent option for proximal ureteral stricture. Our experience is encouraging, and it will find wider application in the complex ureteral lesion.
