Significant Bilateral Calcification over a Neglected Ureteral Stent: About a Case Managed Endoscopically

Abstract

Ureteral stents are integral parts of many procedures in endo-urology. Neglected stents can be associated with significant complications like serious encrustations, stone formation, recurrent urinary tract infections and hematuria. One of the known complications that poses a huge challenge to the urologist to manage is Calcification. The main risk factors for calcification of this stent are low education, time of use, sepsis, pyelonephritis, chronic kidney disease, recurrent or residual kidney stones, congenital and metabolic abnormalities, and malignant ureteral obstruction due to hyperuricosuria and chemotherapy. When removal by cystoscopy is not possible due to calcification, another procedure is required. We are reporting a case of significant bilateral double J-stent calcification in a 33-year-old patient who had kept bilateral double J stents placed for lithiasis for 3 years. Bilateral low back pain associated with hematuria was the main presenting complaints. biologically the renal function was normal. The CT scan revealed calcified bilateral double J probes along their entire length. The management was endoscopic in two sessions consisting of laser fragmentation of the calcifications and removal of the fragmented ureteral stent. Post-operative follow-up was simple.
