Abstract

To assess the influence of the method for stent placement, the duration of stenting, and the presence of bladder drainage on the complication rate of open pyeloplasty. Patients and methods: Complications were, retrospectively, compared in 228 consecutive open pyeloplasties performed at institution A using a trans-pyelostomic 6-Fr splint/stent for 5 days and no bladder drainage, and 150 consecutive open pyeloplasties performed at institution B using a trans-nephrostomic 6-Fr splint/stent for 9 days plus bladder drainage. Results: Median age at surgery was comparable between groups. The overall complication rate was 13% and was comparable at the two institutions, but for the presence of perioperative bleeding that was more common when the stent was placed trans-nephrostomically (institution B) and the rate of stent dislodgements, which was lower at institution A, perhaps due to some technical details aiming to prevent any inadvertent traction on the stent. Additional procedures, such as double J internal stent insertion, were required in <2% of cases. Conclusions: A 5-day period of stenting after open pyeloplasty is generally enough. Trans-nephrostomic and trans-pyelostomic stent placement is equally effective. However, the former can be associated with a slightly higher bleeding rate. Details during stent placement are keys to avoid postoperative dislodgement and malfunctioning. Systematic bladder drainage seems unnecessary
