[Bilateral femoral neuropathy after prostatectomy. Case report and bibliographic review]. / Neuropatía femoral bilateral tras prostatectomía. Presentación de un caso y revisión del tema.

OBJECTIVE: To report one case of postoperative lateral femoral neuropathy presenting after a retropubic radical prostatectomy. We review the topic. METHODS: We describe the case of a 72-year-old patient undergoing radical prostatectomy. Combined anesthesia, general and spinal, was given. A self-retaining automatic retractor (Omnitract) was employed. In the immediate postoperative period the patient presented bilateral femoral neuropathy, with difficulties for knees extension and hips flexion, diminished patellar reflex, and absence of sensitivity in the anterior area of the thighs. MRI was performed to rule out spinal pathology. RESULTS: The symptoms improved a lot within a week, completely recovering after two months. CONCLUSIONS: Femoral neuropathy is a rare complication after pelvic surgery. In our case we believe it was secondary to nerve compression by the retractor.

[Spontaneous rupture of a simple renal cyst to the pyelocalyceal system. Evolution from Bosniak I to IIF]. / Ruptura espontánea de quiste renal simple en el sistema pielocalicial. Evolución desde Bosniak I a IIF.

OBJECTIVE: To report the spontaneous rupture of a renal cyst into the adjacent pyelocalyceal collecting system. METHODS: We present the case of a 47 year old woman with a 17 centimeter simple renal cyst (Bosniak I) as well as ipsilateral nephrolithiasis. The patient had a febrile urinary tract infection with flank pain. A subsequent CT scan revealed that this cyst spontaneously ruptured into the renal pelvis. RESULTS: Follow up evaluations showed the former cyst has decreased in size and contain thick and nodular calcifications. At present it is a Bosniak IIF cyst. CONCLUSION: Simple renal cysts can spontaneously rupture and drain into the adjacent renal collecting system.

[Bilateral multiple renal oncocytoma. Case report and review of the literature]. / Oncocytome rénal multiple bilatéral. Revue de la littérature a propos d'un cas.

The authors report the case of a 75-year-old man presenting with prostatic syndrome. Ultrasound assessment revealed multiple bilateral solid renal lesions that were confirmed by computed tomography. It was decided to perform bilateral percutaneous biopsy of the masses. The histological diagnosis was that of oxyphilic adenoma with an oncocytic appearance compatible with oncocytoma. In view of the histology and the multiple lesions, none of which was larger than 5 cm, it was decided to perform watchful waiting which did not reveal any change in size with a follow-up of 4 years. Although renal oncocytoma is relatively frequent, only 19 cases of bilateral multiple renal oncocytomas have been published in the world literature. The authors present a new case and review the current state of this entity.

[Idiopathic progressive bilateral ureteral stenosis]. / Estenosis ureteral bilateral progresiva e idiopática.

OBJECTIVE: To report one case of progressive bilateral ureteral stenosis without demonstrable etiologic cause. METHODS: We diagnosed and treated a 73-year-old female patient who developed progressive bilateral distal ureteral stenosis without a demonstrable cause. RESULTS: Surgery was carried out and the pathologic study showed a bilateral ureteral stenosis secondary to fibrosis and chronic unspecific inflammation. CONCLUSIONS: Idiopathic ureteral stenosis is a rare clinical picture, more if progressive and bilateral.
