“…For most of the 20 th century it was performed as an open operation, but since the end of the last century, A-H pyeloplasty has been used as a minimally invasive procedure – the first laparoscopic pyeloplasty was done in 1993 by Schuessler et al , as well as by Kavoussi and Peters, and the first robotic approach was performed in 2002 by Gettman et al [ 2 – 4 ]. Since then, minimally invasive pyeloplasty has become a well-studied, commonly used technique among urologists, with a success rate of over 90% [ 5 , 6 ].…”

IntroductionAnderson-Hynes (A-H) dismembered pyeloplasty has remained nearly unchanged since its introduction in 1949. The authors present a modification of the uretero-pelvic anastomosis as described by Anderson and Hynes. The new approach, called the W-type suture, is thought to be more watertight and associated with fewer complications than the original.AimTo assess the effectiveness of the modification of Anderson-Hynes dismembered pyeloplasty named the W-type suture.Material and methodsThe research is a retrospective study of 99 patients who underwent laparoscopic A-H pyeloplasty. In 49 patients unmodified laparoscopic A-H pyeloplasty was carried out. Fifty patients underwent laparoscopic A-H pyeloplasty with the anastomosis made using the aforementioned W-type suture. To assess the effectiveness of the W-type suture, we compared urine leakage duration – a direct indicator of anastomosis tightness – and frequency of postoperative complications.ResultsThe mean duration of urinary leakage was 3 ±1.16 days for the W-type suture anastomosis group and 3.57 ±1.14 days for the unmodified A-H pyeloplasty group (p < 0.05). The frequency of post-operative complications did not statistically significantly differ between the groups except for fever (18.4% vs. 4%; p < 0.05).ConclusionsThe analysis of the collected data showed that the W-type suture might be a promising alternative to a traditional approach of performing the ureteropelvic anastomosis. Further research should be done to minimize biases present in this study, which might have influenced our results.

“…Pyelo-ureteral junction syndrome (PUJS), also known as primary hydronephrosis, is a common cause of urinary malformation in the upper urinary tract [1–4]. It is characterized by a narrowing of the junction between the pelvis and the ureter [1, 2, 4–6]. PUJS may result from an intrinsic, functional, congenital abnormality of the ureteral wall or extrinsic compression more often by a lower polar vessel [2, 3, 6].…”

BackgroundPyelo-ureteral junction syndrome (PUJS) is a frequent congenital malformation. We report the surgical management of PUJS by pyeloplasty according to Anderson-Hyne-Kuss’s procedure at the Zinder National Hospital..MethodsThis was a retrospective study from January 2013 to December 2016 (4 years), including patients who have undergone surgery for PUJS.ResultsTwelve (12) cases of PUJS had a surgery among which 66.7% were men with an average age of 32.5 ± 7.6 years. The clinical symptomatology was lumbar pain or renal colic in 92.3% of cases. This pain had evolved for more than 2 years for 58.3% of the cases. Ultrasound coupled with intravenous urography or CT-scan was performed to confirm the diagnosis of PUJS in 58.3 and 41.7% of cases. The average serum creatinine level at admission was 181.25 ± 67.3 μmol/L [Lab reference range: 53–97 μmol/L]. The Anderson-Hynes non dismembered pyeloplasty is used for all the patients. The release of a crossing lower pole vessel was performed in 25%, pyelolithotomy in 16.7%. The average surgery time was 118.3 ± 20.7 min. The average hospital length of stay was 10.8 ± 3 days. Immediate postoperative complications were recorded in 33.3% (n = 4). Postoperative outcomes were considered good by disappearance of clinical, biological and radiological signs.ConclusionThe Anderson-Hynes non dismembered pyeloplasty gives good results and provides a successful alternative in an environment where laparoscopy and robotic surgery are not developed.
