Encrustation of the Ureteral Double J Stent in Patients with a Solitary Functional Kidney - a Case Report

Abstract

Introduction:The efficacy of ureteric stents in the management of various urological conditions causing the upper urinary tract obstruction has been extensively proven, and their contribution to urology remains enormous. The clinical use of ureteric stents is associated with several complications. “Stent syndrome,” encrustation, migration and urothelial hyperplasia are the most common problems related to long-term ureteral stenting.Case report:This work presents an interesting case from our practice: a complete encrustation of a classical polyurethane double J stent two and a half months after its initial instillation, in a 70 year old man, with a solitary functioning kidney, as well as successful removal of it by using a simultaneous treatment of extracorporeal lithotripsy and ureteroscopy with a contact disintegration of encrustations and with percutaneous nephrostomy, as an auxiliary procedure for providing of additional urine derivation.Conclusion:These problems can be overcome by the introduction of new advanced ureteral stent designs and biomaterials.

Forgotten double J stent with maximum stone burden

“…For the management of mild encrustation, several studies have reported the role of ESWL followed by retrograde extraction of the DJ stent. In patients with moderate-tosevere encrustations and stone presence, modalities such as transurethral Cystolithotomy (CLT), ureteroscopy, and PCNL are used [13,14]. It has been suggested in a number of studies that the distal part of the stent should be removed first, followed by the proximal end [15].…”

Surface analysis of ureteral stent before and after implantation in the bodies of child patients

“…After surgery, the implantation of a double-J ureteral stent may be needed. There are absolute indications for stent insertion, which include relief of obstructed pyelonephritis, bilateral ureteral obstruction, ureteric injuries, and post-treatment of urolithiasis in patients with a solitary kidney [ 3 , 4 ]. As no ideal stent, many problems of stent migration, occlusion, encrustation, fragmentation, and stone formation were noticed.…”

Fibrin glue as a sealant in stentless laparoscopic pyeloplasty: A randomised controlled trial

“…Many surgeons recommend stenting to prevent urine leakage and to maintain the anastomosis patent, as postoperatively oedema at the anastomotic site may lead to occlusion of the lumen [3]. However, indwelling ureteric stents can cause problems and significant adverse effects, such as discomfort, infection, migration, and encrustation, which can lead to significant morbidity [4]. Additionally, removing them requires an additional procedure and exposure to anaesthesia.…”
