Poorer outcome in Polynesian patients with prostate cancer treated with definitive conformational radiation therapy.

Purpose: To compare freedom from biochemical failure (FFBF) of French Polynesian (FP) and Native European (NE) prostate cancer patients after definitive conformal radiotherapy (RT).

Patients And Methods: Data were reviewed from medical records of 152 consecutive patients (46 FP and 106 NE) with clinically localised prostate cancer treated with definitive RT. Neoadjuvant androgen deprivation therapy (ADT) was used in 22% of cases.

[Composition of renal stones currently observed in non-industrialized countries].

Unlabelled: Up until relatively recently, renal stones in developing countries were considered to be very different from those observed in industrialized countries, essentially characterized by the predominance of phosphate and urate stones, while the predominant stones in industrialized countries are calcium oxalate stones. To verify whether this difference in the epidemiological profile is still observed today, we analysed renal stones collected in various regions of the globe and compared their composition to that of stones observed in France.

Material And Method: 1,042 stones were collected between 1991 and 2000 from 14 different countries or geographical zones: Sub-Saharan Africa (Cameroon, Mali, Senegal), North Africa (Algeria, Morocco, Tunisia), South America (Brazil, Paraguay), Asia Minor (Pakistan, Turkey), Far East (China, Laos, Vietnam) and French Polynesia (Tahiti).

[Late rejection of Mersylene mesh used for promontory fixation with colonic obstruction].

We describe a case of colonic obstruction in a 48-year-old woman, 3. 5 years after surgery for genito-urinary prolapse. The causal agent was the Mersylene mesh used for promontory fixation.

[Treatment of complicated renal colic in patients treated with indinavir: value of double J stents].

Objective: Evaluation of the treatment of complicated ureteric stones in patients treated with indinavir.

Patients And Methods: From March 1997 to May 1998, 10 patients (7 males, 3 females, aged 30 to 56 years), treated by triple combination therapy for HIV infection, were drained for stones attributed to indinavir (CRIXIVAN), which had become obstructive and complicated. The duration of treatment with indinavir ranged from 14 days to 2 years.

[Review on the use of CO2 in laparoscopy surgery].

Laparoscopic surgery is one of the treatment modalities available to urologists, who must be familiar with the concepts of the physiology of CO2 and its clinical consequences. CO2 is absorbed during insufflation, leading to hypercapnia, reaching a steady-state from the 20th minute. The insufflation pressure must be between 10 and 14 mmHg.
