[Inflatable penile prosthesis: satisfaction rate, result, prognostic factors. Prospective study on 50 primooperated patients in CHU of Nice between 2000 and 2009]. / Implants péniens hydrauliques: enquête de satisfaction, résultats et complications. Étude rétrospective portant sur 50 patients consécutifs primo implantés au CHU de Nice entre 2000 et 2009.

OBJECTIVE: To evaluate satisfaction rates and results in patients with penile prosthesis (5 PP). MATERIALS AND METHODS: From January 2000 till 2009, 50 patients with organic erectile dysfunction (ED) were implanted with hydraulics penile prosthesis by the same surgeon. Medical records were collected retrospectively. We analysed demographic characteristics, type of prosthesis used, per- and postoperative complications, prosthesis explantations and satisfaction rate measured by EDITS modified. RESULTS: Mean age of patients was 60.2 ± 8.46 years (35-75). Thirty implanted patients (60%) were diabetics. We used a peno-scrotal incision in all patients. Three types of prosthesis were used; AMS Ambicor, AMS 700, Titan OTR. A bi-compartment and three-compartment prosthesis were implanted respectively in 24 and 26 patients. The prosthesis was retrieved in two patients secondary to a mechanical failure, in three patients for prosthesis erosion, in two patients for prosthesis infection. In four out of the seven explanted patients, a second prosthesis was implanted. The EDITS questionnary was realized by telephonic interview in 47 patients after a mean follow-up of 45 months (5-114). The response rate was of 83%. The satisfaction rate was of 81%. CONCLUSION: In our series, the satisfaction rate was better for the three-compartment prosthesis. After 45 months of follow-up, 73% (31/42) of patients had a functional prosthesis. The non-satisfaction most frequently found were patients who have complications as sepsis; mechanical failure, and prosthesis erosion, and subjective feeling of penile length reduction.

[Clinicopathological study and immunohistochemical expression of CA9 in cystic multilocular renal cell carcinomas]. / Étude anatomoclinique et de l'expression immuno-histochimique de CA9 dans les carcinomes kystiques multiloculaires du rein.

OBJECTIVE: Multilocular cystic renal cell carcinoma has been considered as a distinct subtype of clear cell renal cell carcinoma according to 2004 WHO classification. CA9 has proven to be a diagnostic and prognostic marker for clear cell renal cell carcinoma, but the study has been limited to solid tumors. The aim of this article was to analyse the clinical features of multilocular cystic renal cell carcinoma with focus on CA9 expression. PATIENTS AND METHODS: Nine multilocular cystic renal cell carcinomas were found. Their age was from 33 to 74 years old with a median of 54 years. There were five men and four women. The computerized tomography was analyzed. There were three total nephrectomies and six partial nephrectomies. The follow-up ranged from five to 102 months with a median 56 months. Immunohistochemical staining was performed on surgical samples to detect CA9 expression. RESULTS: There were seven pT1a, one pT1b and one pT2; four grade 1 and five grade 2. The Bosniak classification was: one B2F, six B3 and two B4. In CT examination, all tumors showed a hypodense mass. Seven out of nine showed multiple intern septa, more or less thick and vascularized with an enhancement after injection of contrast. No metastasis or relapse was found during follow-up. Eight out of nine multilocular cystic renal cell carcinomas expressed strongly CA9. CONCLUSION: Multilocular cystic renal cell carcinoma was a low malignant tumor with a good prognosis. The diagnostic criteria based on the WHO classification 2004 should be adopted in routine. CA9 could be a new diagnostic marker for this tumor.
