Morbidity and long-term results of subcutaneous pyelovesical bypass in chronic ureteral obstruction
Copyright © 2021 Elsevier Masson SAS. All rights reserved..
BACKGROUND: We present the long-term results and complications of the DETOUR® prosthesis, a permanent subcutaneous pyelovesical bypass for the treatment of ureteral obstruction.
PATIENTS AND METHODS: Between 2006 et 2018, 34 prosthesis were implanted in 28 patients (mean age 65,8 years) with ureteral obstruction of malignant or benign etiologies. The prosthesis, composed to an inner tube of silicone and an outer tube of expanded polytetrafluoroethylene, is placed subcutaneously between the kidney and the bladder. We are performed infrared spectrophotometry and scanning electron microscopy on two removed prostheses to explore the prosthetic encrustation.
RESULTS: The average follow-up was 25,8 months (Maximum: 64 months). Stent revision was required for early bladder fistula in three patients. The major long-term complications were infection (46%), obstruction (3 patients) and bladder fistula (7 patients). The most frequently infection are non-severe, but two patients died from septic shock after fungic colonization of the prosthesis. The infrared spectrophotometry and scanning electron microscopy analysis showed that the obstruction was favored by urinary infection and an alkaline medium. The functional prosthesis rate at 1,2 and 3 years was 94%, 71% and 62%, respectively.
CONCLUSION: The DETOUR® subcutaneous extra-anatomical urinary bypass is an effective and minimally invasive alternative to permanent percutaneous nephrostomy, for both malignant and benign ureteral obstructions in selected patients.
