- Abstract
Introduction: There are various alternatives available for renal pelvis drainage following pyeloplasty. One of them is the use of an internal-external diversion stent, which according to our protocol, is knotted 48 hours following surgery, prior to discharge, and removed 7 days later on an outpatient consultation basis, with no sedation or analgesia required., Objective: To analyze the results of patients under one year of age who underwent open pyeloplasty associated with an outpatient internal-external diversion stent., Materials and Methods: A retrospective, descriptive analysis of 28 patients (31 renal units) undergoing surgery from 2011 to 2021 was carried out. Diagnostic methods, indications, surgical approach, and postoperative progression were assessed., Results: 28 patients (23 male) prenatally diagnosed with hydronephrosis confirmed by ultrasonography and/or renogram underwent pyeloplasty at a median age of 3 months (15 days-11 months). Pyeloplasty was conducted according to the Anderson-Hynes technique or dismembered pyeloplasty in 28 renal units, and according to the Culp-DeWeerd technique or spiral flap in 3. In all cases, an internal-external diversion stent was used according to our protocol. Mean hospital stay was 3.5 days (2-7 days), with a good postoperative progression. 2 patients had complications (urinary infection requiring intravenous antibiotics, and pyonephrosis requiring re-pyeloplasty)., Conclusions: Using an internal-external diversion stent following pyeloplasty in patients under 1 year of age with ureteropelvic junction obstruction is a simple and safe option that allows for early discharge with outpatient management. It also avoids a second general anesthesia for drainage catheter removal purposes.
