Summary
Open pyeloplasty for ureteropelvic junction obstruction (UPJO) achieved an 84% success rate in this review. Complications like infection and inadequate suturing can lead to UPJO recurrence.
Area of Science:
- Urology
- Pediatric Surgery
- Nephrology
Context:
- Retrospective review of 23 patients (25 kidneys) undergoing open pyeloplasty for ureteropelvic junction obstruction (UPJO) between 1980 and 2001.
- Analysis focused on identifying factors contributing to treatment failures.
Purpose:
- To evaluate the long-term outcomes and identify failure modes of open pyeloplasty for UPJO.
- To discuss techniques and complications associated with open pyeloplasty.
Summary:
- The study included 17 men and 6 women, aged 3 months to 69 years, with a mean follow-up of 8.6 years.
- Anderson-Hynes pyeloplasty was the most common procedure (22 kidneys).
- Overall success rate was 84% (21 of 25 renal units). Four cases of persistent UPJO were managed with repeat pyeloplasty, nephrectomy, or balloon dilatation.
Impact:
- Identifies infection and prolonged urinary drainage as potential causes of periureteral fibrosis, leading to UPJO recurrence.
- Highlights inadequate suturing as a cause of anastomotic granuloma formation.
- Provides insights into managing recurrent UPJO after primary open pyeloplasty.
