AI Article Synopsis
- A study analyzed 28 patients under one year old who underwent pyeloplasty with an internal-external diversion stent for renal drainage, aimed at assessing postoperative progress.
- Results showed a median patient age of 3 months, with a mean hospital stay of 3.5 days and low complication rates, highlighting the effectiveness of the procedure.
- The internal-external diversion stent offers a safe, simple, and efficient method of renal drainage that facilitates early discharge and minimizes the need for additional anesthesia during catheter removal.
Article 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.

Article Synopsis
- - Ureteral obstruction after urinary diversion is a common issue, usually treated with the placement of a ureteral stent through a nephrostomy.
- - A 64-year-old man with a history of rectal cancer and urinary diversion experienced bilateral ureteral obstruction due to postoperative adhesion, leading to bilateral nephrostomy.
- - Attempting both antegrade and retrograde approaches, the rendezvous technique allowed successful placement of an internal-external drainage catheter, helping the patient avoid permanent nephrostomy and maintaining his quality of life.
