[How to plan the treatment of prostatic adenoma today?]

Surgical treatment, mainly transurethral resection of the prostate, still remains the reference treatment for benign prostatic hyperplasia (BPH). Two studies conducted in the Urology Department of the Pitié-Salpêtrière Hospital have tried to define certain characteristics of this surgery. The first study tried to evaluate the long-term outcome of patients operated for benign prostatic hyperplasia. Analysis of 881 replies to a questionnaire sent to 3,147 patients operated for BPH (between 1976 and 1989) assessed functional status (by Madsen's symptom score), quality of life (by Fowler's method), and sex life (by two specific questions), with a follow-up ranging from 5 to 14 years. At this follow-up, 90% of patients declared to be satisfied with their voiding status, 95% considered their quality of life to be excellent and about 50% had maintained a sex life. The second study was designed to evaluate the morbidity of this treatment in elderly patients. A group of 33 operated patients over the age of 80 was compared to a control group composed of 66 patients between the ages of 60 and 70 years, treated in a similar way, in the same centre and in the same year. Morbidity was higher in the first group, but age itself did not appear to constitute a poor prognostic factor for surgery; it only intervenes by allowing certain complications of benign prostatic hyperplasia (acute retention) to create emergency situations complicating the perioperative period. Following demonstration of the short-term and long-term efficacy of this conventional surgery, many new technologies were subsequently developed in order to reduce perioperative discomfort, anaesthetic requirements, duration of catheterization and hospital stay. Some of them constitute a new approach to endoscopic surgery, such as prostatic tissue vaporization techniques (electrovaporization, laser contact vaporization), which have a comparable efficacy to that of TURP, while reducing bleeding, catheterization time and hospital stay. However, the duration of postoperative irritative symptoms is much longer. Other techniques use a thermal effect to obtain coagulation necrosis of prostatic tissue, using various energy sources: microwaves (thermotherapy), laser (interstitial laser), radiofrequency waves (TUNA). These techniques are perfectly adapted to outpatient surgery with local or regional anaesthesia. They do not interfere with continence, sexual function, but may be followed by high dysuria or retention rates, with a variable cathererization time, sometimes several weeks. Finally, urethroprostatic stents are easy to insert, provide a solution in critical situations and have replaced old indwelling catheters. The current choice of treatment therefore comprises several approaches: more effective, but still purely symptomatic medical treatment, safe conventional surgery providing excellent long-term results, but generating a certain perioperative discomfort and a certain morbidity, or, on the contrary "minimally invasive" techniques, greatly simplifying the therapeutic procedure, but whose morbidity has not yet been determined and whose results are still uncertain.
