A Conservative Approach to Inflammatory Myofibroblastic Tumor of the Bladder: A Case Report and Review of Literature.

Inflammatory myofibroblastic tumors (IMTs) are particularly rare tumors that have been described in various anatomic locations, of which the urinary bladder is the most common. These benign tumors are amendable to conservative therapy but are notoriously difficult to diagnose given their mimicry of malignant sarcomas and sarcomatoid carcinomas, making an accurate diagnosis paramount to spare a patient radical and unnecessary treatment. We hereby present the case of a 37-year-old female patient who was diagnosed with an IMT of the urinary bladder during workup for painless gross hematuria.

[Evaluation of stone size before flexible ureteroscopy: Which measurement is best?].

Purpose: To retrospectively assess the clinical utility in ureteroscopy (URS) planning of radiological parameters as predictor of stone-free status after a single flexible ureteroscopy.

Material: Sixty-seven patients with renal stones treated by flexible URS were retrospectively evaluated. To assess the clinical utility of radiological parameters, relationships between stone-free (SF) status and stone burden (maximal diameter, calculated area, calculated volume, cumulative diameter, and tridimentionnal volume [V3D]) were analyzed using the area under the receiver operating characteristics curve and logistic regression.

[Medical complications of extracorporeal lithotripsy].

Extracorporeal shock wave lithotripsy (ESWL) is one of the most frequently applied procedures for the treatment of urolithiasis. ESWL breaks and splits stones by the means of repeated acoustic shock waves. Despite its non invasive nature, ESWL has been intuitively associated with potential complications, mostly related to residual stone fragments.

[Acute renal failure following rectosigmoidoscopy].

We report the case of a 24-year old man with a past history of vesical extrophy and ureterosigmoidostomy in childhood, admitted with acute left flank pain and acute renal failure. The complaints started the day following the endoscopic resection of a sigmoid polyp. The stricture of the ureterosigmoid junction was diagnosed by intravenous urography.
