Patient and Method: This is a 3-year prospective descriptive study from January 1, 2018 to December 31, 2020. It focused on a sample of 21 patients, who had undergone pyeloplasty according to Küss-Anderson-Hynes. Results: The averages age of the patients was 24.24 years. Lumbar pain was the main reason for consultation in 71.43% of cases. pyeloplasty according to Küss-Anderson-Hynes alone was performed in 76.20% of cases. It was associated with lower pole vessel uncrossing in 14.29% of cases and in 9.52% of cases with pyelolithotomy. The main Postoperative complications consisted of surgical site infections (23.81%) and fistula of the pyelo-ureteral junction (9.52%). The result of the pyeloplasty evaluated after three years, was qualified as good in 13 patients (86.67%), conversely the result was declared bad in 2 patients or 13.33%. During the follow-up period, postoperatively, we had lost sight of 6 patients. Conclusion: Pyeloplasty according to Küss-Anderson-Hynes in addition to its excellent results reported by the literature was the only therapeutic alternative performed during this study. However, its indications are considerably reduced with the advancement of laparoscopy.展开更多

The standard treatment is open pyeloplasty using the Kuss-Anderson technique. Because of the minimally invasive nature of the laparoscopic approach, it has become the approach of choice for the management of this pathology. We present the results of laparoscopic transperitoneal pyeloplasty used in the management of PUJS. Materials and Methods: This was a retrospective study from 2015 to 2020, including 26 patients who underwent laparoscopic transperitoneal pyeloplasty for PUJS. Results: Twenty-six patients, including 18 (69.2%) men and 6 (30.8%) women, with a mean age of 35.42 ± 13.62 years, were treated. Renal colic was the primary symptom in the majority of the cases (22, 84.6%)). The diagnosis was confirmed in all patients through an abdominal CT scan, which revealed that all 26 patients had hydronephrosis. Half of the patients (50.0%) were classified as Valayer-Cendron Type II, and eight (30.8%) patients had associated stones. Seventeen (65.4%) patients had pathologies on the left side, and all patients were treated using the Kuss-Anderson technique with a median operating time of 108.5 (90.0 - 136.0) minutes. The uncrossing of lower pole vessels was performed in 10 patients. The average duration of hospitalisation was 2.23 ± 0.82 days. No conversion was observed, and after an average follow-up of 53.69 days, the success rate was 92.3%. Conclusion: Laparoscopic pyeloplasty is a minimally invasive technique of choice for the treatment of pyelo-ureteral junction obstruction. It is dependable, repeatable, and produces good functional outcomes that are equal to those of traditional surgery.展开更多
