[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.

[Wunderlich syndrome. Clinical and therapeutic aspects of a long-term experience].

Introduction: Wunderlich's syndrome is defined as a clinical manifestation secondary to sudden spontaneous rupture of renal parenchyma in the absence of injury, resulting in hemoretroperitoneum. This syndrome may occur in patients with benign or malignant neoplasm of the kidney, arterial venous fistulae, immunovasculitis and other phlogosis of the kidney.

Materials And Methods: We present 19 cases of acute spontaneous hemoretroperitoneum or Wunderlich's syndrome diagnosed from 1996 to 2009, related to the following conditions: 7 renal carcinomas, 4 angiomyolipomas, 2 adrenal hemorrhages, 1 bleeding polycystic kidney, 2 hemorrhagic renal cysts and three cases of immunovasculitis.
