03:36 PM Abstract No. 415 Percutaneous nephrostomy versus double-J ureteral stent: does order matter?

The double J stent is widely used in urological endoscopic surgery with different indications (ureteral stenosis, ureteropelvic junction obstruction, retroperitoneal tumor or fibrosis) and can be a subject to multiple complications including migration, encrustation, stone formation and fragmentation which is a rare complication. We are reporting a rare case of a 42-years-old, followed for cervical cancer since 2018 revealed by an acute obstructive renal failure drained by a left double J ureteral stent (of long duration) and right percutaneous nephrostomy. The patient maintained the double J stent for 2 years. On clinical examination there was a lumbar tenderness on the left side and a hardened vaginal cervix on bimanual vaginal examination. The patient underwent a renovesical ultrasound showing a minimal left ureterohydronephrosis. The uroscanner with reconstruction revealed a fragmented double J stent on the left side.

Ureteric Stent

Abstract Background Ureteric stricture is a common and salvaging complications after renal transplantation. Two treatment methods are usually used, retrograde ureteral stent placement and percutaneous nephrostomy. The former has a higher failure rate, the latter has a great risk. Therefore, a safe and reliable treatment is needed. Case presentation A technique of retrograde insertion of ureteral stent was established, which was applicable in three transplant recipients with post-transplant ureteral stenosis, and the data was retrospectively recorded. The patients are 2 men and 1 woman, ages 44, 27 and 32 years. These patients underwent a total of five times of retrograde insertion of ureteral stent between 2018 and 2019. None of these patients had any postoperative complication, but all patients had complete recovery from oliguric status within two weeks. Conclusions The retrograde ureteric stent insertion by percutaneous suprapubic access to the bladder (RUS-PSAB) was demonstrated feasibility and safety in a case series with short-term follow-up. However, larger prospective studies are needed.

Analysis Survival

Background: Malignant ureteral obstruction (MUO) is variable in presentation and there is no consensus on its management, especially when caused by gastrointestinal (GI) malignancies. Our aim was to describe our experience with this oncological complication. Methods: We retrospectively analyzed the outcomes of ureteral stent and nephrostomy tube (NT) positioning for GI-related MUO from 2010 to 2020. We performed descriptive analysis, survival analysis, and uni- and multi-variate analysis. Results: We included 51 patients. NT was mainly used when bladder involvement occurred and when MUO revealed an ex novo cancer diagnosis. Survival was poorer in patients with new diagnoses and in those receiving no treatment after decompression. Moreover, MUO caused by upper-GI tumors was related to shorter overall survival. Conclusions: GI tumors causing MUO should be considered of poor prognosis. Treatment decisions should be weighted accurately by both specialists and the patient.
