Pseudocystic ureteritis. Apropos of a case

The authors report one case of ureteritis cystica in a young adult. The diagnosis was made by intravenous urography and confirmed by histologic examination. The patient was treated surgically (nephro-ureterectomy). The etiopathogenic, clinical and therapeutic aspects are discussed with a review of literature.

Lithiasis and ectopic pelvic kidney. Therapeutic aspects

Kidney in ectopic position is dysplasic, and associated to other malformations. The advent of a lithiasis in these conditions rises questions about therapeutic options. We report on five observations of pelvic ectopic kidney with urinary lithiasis. Patients were aged from 16 to 42 years. Kidney was non functional in two cases, or with normal appearance sized 10 to 12 cm. We performed total nephrectomy in two cases, pyelolithotomy in the other cases. Surgical approach was subperitoneal via iliac route. A dismembered pyeloplasty was associated in one case. All patients did well. Radiologic control at 6 and 12 months showed no recurrence in a well functioning kidney. Surgical lithotomy is advocated as a treatment in urinary lithiasis affecting ectopic kidney. It is an easy procedure which permits correction of other associated malformations.     

Bilateral testicular metastasis of cancer of the prostate

Testicular metastasis of prostate cancer rarely occurs. Bilateral localization is exceptional. We report a new case of prostate adenocarcinoma with bilateral testicular metastasis. The diagnosis was made on clinical and ultrasonic arguments, and confirmed on the pathological specimen. Treatment consisted in a bilateral orchidectomy, associated with nonsteroid androgens.     

Cystic cancer of the kidney

Cystic renal cancer is uncommon and raises real preoperative diagnostic problems, requiring the use of medical imaging, and sometimes even surgery. The authors report 3 cases of cystic renal cancer in 2 men and 1 woman, aged 87, 67 and 20 years, respectively. Three patients presented with the urological triad (haematuria, pain and lumbar mass). Ultrasonography suggested the diagnosis of cystic cancer in all 3 cases. Computed tomography was performed in 2 patients and more precisely confirmed the ultrasound findings. Selective arteriography, performed in one patient, confirmed the hypothesis of malignancy. Surgical exploration resulted in radical total nephrectomy. Histology confirmed the diagnosis of adenocarcinoma. The course was favourable in 2 cases after a follow-up of 4 years. One patient presented a local recurrence with pulmonary metastases 6 months after the operation. A review of the literature illustrates the diagnostic difficulties of this form of renal cancer.
