[A case of intravesical migration of an intrauterine device detected 14 years later].

We report the case of a patient arrived because of urological symptoms characterized by terminal hematuria, strangury and dysuria due to migration into the bladder of an intrauterine contraceptive device (IUD) placed 14 years before and penetrated into the bladder with formation of lithiasis. These cases have already been described in literature, but the particular feature of this case is that the patient had been pregnant and had a eutocic delivery, she never voluntarily removed the IUD and nor was it found during a gynecologic laparoscopy. The patient underwent the surgical removal of the IUD and of the bladder stone, without detecting adjacent connective routes between uterus and bladder.

[Transurethral enucleation of bladder paraganglioma].

Paraganglioma of the urinary bladder is a rare neoplasm that derives from ganglion cells located in the bladder wall and may morphologically simulate a urothelial carcinoma. The authors present the case of a vesical paraganglioma incidentally detected by ultrasound, and entirely removed by transurethral approach from detrusorial wall. Conventional approaches include surgery (partial cystectomy) or laparoscopic procedures, with inspection by transurethral endoscopy; in this case we wanted to avoid the combined approach considering the lesion diameter and the possibility of an easy removal.

[Three cases of renal cell carcinoma with sarcomatoid differentiation].

Renal cell carcinoma with sarcomatoid differentiation has an incidence of 4-6%. It occurs more frequently with clinical advanced presentation in relation to the greater biological aggressiveness. This variant was also found both in transplanted kidneys and in patients with von Hippel-Lindau syndrome.

[A case of chronic schistosomiasis four years after infestation].

Authors present a case of bilharziosis incidentally diagnosed in a patient undergoing TURB for suspected bladder cancer. The patient, who in 2005 had gone to Malaysia, had been suffering from recurrent hemorrhagic cystitis since 2007, which were treated with antibiotic therapy. In November 2009 he presented to our observation for persistent hematuria, underwent ultrasound examination, fibroscopy and TURB diagnostics for suspicious lesions.

[Indications and limits to endourologic procedures for endometriosis of the urinary tract].

Introduction: The incidence of Urinary tract endometriosis (UTE) ranges from 1% to 3%; bladder is the most affected organ (85% of UTE), followed by ureter (12 - 14% of UTE), for which we distinguish an intrinsic very rare form and an extrinsic variety most frequently occurring in advanced pelvic endometriosis.

Materials And Methods: From 1997 to 2010, 33 surgical procedures for urologic endometriosis were performed, involving the urinary tract, in 28 patients with mean age of 31 years (25-43). The localization of endometriosis were: 7 cases in the bladder, 2 cases in the vesicoureteral tract, and 19 cases of ureteral tract only.
