Long-term follow-up of patients after pyeloplasty for ureteropelvic junction obstruction
Insights
Ureteropelvic junction obstruction treatment in 94 patients showed 96.2% satisfactory clinical results. Most patients experienced good or improved calyceal drainage after pyeloplasty, ureterocalycostomy, or nephrectomy.
Area of Science:
- Pediatric Urology
- Surgical Outcomes
- Renal Pelvis Disorders
Background:
- Ureteropelvic junction obstruction (UPJO) is a common cause of congenital hydronephrosis.
- Surgical intervention is often required to restore proper urinary drainage.
- Long-term outcomes and surgical techniques for UPJO require ongoing evaluation.
Purpose of the Study:
- To evaluate the clinical outcomes of surgical management for ureteropelvic junction obstruction.
- To assess the efficacy of different surgical approaches, including dismembered pyeloplasty, ureterocalycostomy, and nephrectomy.
- To analyze postoperative calyceal appearance and drainage patterns.
Main Methods:
- Retrospective review of 94 patients treated for UPJO between 1976 and 1986.
- Surgical procedures included dismembered pyeloplasty (85 patients), ureterocalycostomy (4 patients), and primary nephrectomy (5 patients).
- Postoperative excretory urography was used to assess calyceal appearance and drainage.
Main Results:
- Overall clinical success rate was 96.2%.
- Dismembered pyeloplasty was the most common procedure (85/94 patients).
- Postoperative excretory urograms showed good drainage in 53.8%, improved drainage in 42.3%, and deterioration in 3.8% of patients.
Conclusions:
- Surgical management of UPJO yields high rates of satisfactory clinical outcomes.
- Dismembered pyeloplasty is an effective primary treatment for UPJO.
- Postoperative calyceal appearance and drainage are important indicators of surgical success.
Abstract:
Between the years 1976 and 1986, 94 patients ranging in age from 2 weeks to 60 years were referred for treatment of ureteropelvic junction obstruction. A dismembered pyeloplasty was performed in 85 patients, ureterocalycostomy in 4 patients and primary nephrectomy in 5 patients. Apart from aberrant vessels found in 14 patients and associated calculi in 12, clinical results were satisfactory in most of the patients (96.2%). The calyceal appearance on the postoperative excretory urogram showed diminution with good drainage in 53.8%, improvement of drainage in 42.3%, and deterioration in 3.8%.
