Fibrosis is the end point of most renal diseases, and several glycosaminoglycans have been shown to attenuate this process. Marine invertebrate glycosaminoglycans with unique structures have opened the possibility to test these new compounds on renal fibrosis. The effect of a fucosylated chondroitin sulfate from an echinoderm marine species is reported with the use of a model of renal fibrosis ...

PURPOSE The aim of this research was to evaluate the efficacy of the cystoscopic extraction and external drainage techniques for unsuccessful antegrade stenting in transplanted severe ureteral obstruction. MATERIALS AND METHODS A total of 26 patients with severe transplanted ureteral obstruction in whom the cystoscopic extraction technique and/or external drainage technique was performed were...

OBJECTIVES To examine the feasibility of early laparoscopic ureteroneocystostomy for ureteral obstruction due to hysterectomy injury. METHODS We retrospectively reviewed a 10-y experience from 2 institutions in patients who underwent early (<30 d) or late (>30 d) laparoscopic ureteroneocystostomy for ureteral injury after hysterectomy. Evaluation of the surgery included the cause of the stric...

Retained ureteral stents in patients lost to follow-up present a challenge to urologists. Patients may present with recurrent flank pain, pyelonephritis, stent migration or encrustation, and ureteral obstruction, with resultant renal failure. Rarely, a long-indwelling period may result in stent fragmentation. Herein, we present a case of a fractured retained ureteral stent noted in a patient lo...
