Antegrade repositioning of Memokath stent in malignant ureteroileal anastomotic stricture (in an ovarian cancer patient)

open access

Case report 

A 64-year-old lady was diagnosed to have locally advanced ovarian carcinoma 5 years prior to presentation. She had undergone debulking surgery with colostomy as well as ileal conduit diversion surgery. She had also undergone two courses of chemotherapy, and was also treated with fulguration that entailed tissue ablation using high-frequency electric sparks. Despite the aggressive treatment of the disease, she developed tumor recurrence that caused right hydronephrosis (and) and hydroureter. Endoscopic examination performed via the ileal conduit showed a 5-cm stricture of the ureteroileal junction caused by tumor infiltration. Balloon dilatation of the malignant stricture was performed, but there was still persistent contrast hold-up seen in the right collecting system. Subsequently, antegrade stenting of the malignant stricture was performed using a 6F double J stent. Unfortunately, there was recurrent distal migration of the double J stent into the conduit, requiring repeated repositioning of the stent under fluoroscopic guidance in the radiology department.....
