%X We present the unusual case of a 32F Silastic drain found inside the urinary tract in a female patient who had previously undergone ileal loop replacement of the left ureter for post-hysterectomy stricture at another Institution, and had subsequently repeated surgery due to persistent hydronephrosis. Radiological findings on plain abdominal X-ray were quite misleading, while CT allowed a correct assessment of the drain features.While double J stents of different lengths, sizes and materials are used in ureteral surgery, the use of Silastic drains has not been previously reported. In light of the present experience we don¡¯t suggest its routinely use.While double J stents of different lengths, sizes and materials are used in ureteral surgery, to the best of our knowledge the use of Silastic drains has not been reported. This uncommon finding is due to the fact that the procedure had been performed by General Surgeons, and is also explained by the size of the intact ileal loop. The poor outcome of bowel segments incorporated into the closed urinary system was reported first more than 30 years ago [1], and at present, only tapered ileum is used for ureteral substitution (Yang-Monti procedure) [2,3].Plain radiography of the abdomen is the diagnostic procedure most commonly performed to assess the position of ureteral stents. Its main advantages are its low cost, technical ease, ubiquitous availability even in small hospitals, very fast imaging time, and relatively low radiation dose. However, while interpretation of X-ray images is usually straightforward in patients with correctly positioned or (at the opposite extreme) grossly displaced ureteral stents, findings can be inconclusive or misleading when nonconventional devices are used or in case of subtle rupture or displacement of ureteral stents [4-6]. In such situations, computed tomography (CT) can provide valuable information that may be vital to make the right diagnosis. In particular, the currently widespread avai
