ABSTRACT

OBJECTIVES: To compare the various Stenting techniques used in ureteropelvic junction (UPJ) surgery and to present a personal series of 54 cases in which the Multipurpose Blue Stent (BARD, ANGIOMED) was used. PATIENTS AND METHOD: Between 1994 and 1998, 54 patients were treated for UPJ obstruction (52 underwent a Anderson-Hynes pyeloplasty and 2 a ureterocalicostomy). The Multipurpose Blue Stent insertion technique is described. The stent is removed on postoperative day 10 in the ward without cystoscopy. RESULTS: Clinical, isotopic and ultrasound improvement was obtained in 98% cases. Seven complications were reported 4 urinary tract infections and 2 stent displacements without noticeable detrimental consequences on the outcome; 1 anastomotic leakage following a ureterocalicostomy requiring a redo operation (which was successful). The average hospital stay was 3 days. DISCUSSION: This stenting method is compared to those reported in the literature and proves to be more satisfactory in terms of hospital stay and removal. CONCLUSION: Postoperative leakage in non-stented operated UPJs is an under-reported but significant complication. Trans-anastomotic stenting has proven to be much safer than non-stenting. The Multipurpose Blue Stent reduces hospital stay and does not require a second hospitalisation to be removed.
