ABSTRACT
PURPOSE: To present our experience and discuss the various endourological approaches for treating forgotten encrusted ureteral stents associated with stone formation. MATERIALS AND METHODS: From July 2006 to December 2008, 14 patients (11 men and 3 women) with encrusted ureteral stents were analyzed. The average indwelling time of the stent was 4.9 years (range 1 to 12). Plain-film radiography was used to evaluate encrustation, stone burden, and fragmentation of the stents. Intravenous urogram and a Tc99m diethylene triamine penta acetic-acid renogram was used to assess renal function. RESULTS: In seven patients, the entire stent was encrusted, in three patients the encrustation was confined to the ureteral and lower coil part of the stent, two patients had encrustation of the lower coil, and minimal encrustation was observed in two patients. Percutaneous nephrolithotomy was performed in 5 cases and retrograde ureteroscopy with intra-corporeal lithotripsy in 9 patients. Cystolithotripsy was used to manage the distal coil of the encrusted stent in eight patients. Simple cystoscopic removal of the stents with minimal encrustation was carried-out in two cases. Looposcopy and removal of the stent was performed in one patient with an ileal conduit and retained stent. Only one patient required open surgical removal of the stent. Thirteen out of 14 patients were rendered stone and stent free in one session. All except two stents were removed intact and stone analysis of encrustation and calcification revealed calcium oxalate and calcium phosphate in the majority of the cases. CONCLUSION: Endourological management of forgotten encrusted stents is highly successful and often avoids the need for open surgical techniques.

Malacoplakia is one of the rare, chronic inflammatory disorders affecting the epididymis and testis. Diagnosis of the same is important as the treatment differs from the other granulomatous lesions in this area. We present a case of malacoplakia involving both the epididymis and testis with a brief review of literature.

Myoepitheliomas of intraoral minor salivary glands are rare and are usually of plasmacytoid type. Myoepitheliomas are considered difficult to diagnose without the aid of ultrastructural and histochemical studies. Here we present a case report of plasmacytoid type of myoepithelioma of palate that was diagnosed by light microscopic examination alone. Considering the non-specificity of ultrastructural and histochemical findings, it is important to pay attention to typical features of plasmacytoid myoepitheliomas to arrive at a diagnosis.
