[Visual laser coagulation for benign prostatic hyperplasia. Preliminary experiences].

A total of 28 patients with symptomatic bladder outlet obstruction due to benign prostatic hyperplasia were treated by visual laser coagulation (VLAP) performed with the Myriadlase sidefiring neodymium: YAG laser fibre at 40 Watts power. The treatment was performed as an outpatient procedure using intraurethral gel anaesthesia and light intravenous sedation and analgesia. Prostatic volume was 32 g (18-90 g), and 650 Joule per gram prostatic tissue (516-1000 J/g) was administered. The patients were evaluated at mean 9.2 weeks. The mean operative time was 34 minutes. The procedure was very gentle, all patients tolerated it well and there was no bleeding. Most patients experienced some dysuria for three to four weeks after the procedure, two had severe symptoms. Two patients remained in retention and required transurethral resection. The rest expressed subjective satisfaction with the results. Peak urinary flow increased from mean 9.0 ml/sec preoperatively to 15.4 ml/sec; a mean increase of 78%. One patient developed clinical urinary tract infection. There were no other complications of clinical significance.

A survey concerning the attitudes of urologists toward prostatism patients.

In a questionnaire all urological units in Norway were asked about: 1. The examinations they routinely used for prostatism patients before deciding upon treatment. 2. How they would score different objective and subjective information about these patients on a scale from 0 to 10. 3. How the physicians classified different prostatism symptoms into categories of weak, moderate and severe. The results were: Urinary retention occurring more than once or residual urine greater than 500 ml was considered an absolute indication for surgery. Agreement about indications for surgery was good for information which received a high median score, but was much poorer for information which received a lower median score. Agreement on how to classify different symptoms into categories according to severity was not good. Using the median classification of symptoms it was estimated that urologists believe that 0.1-5.8% of men over 60 years of age have severe symptoms, 2.1-36.4% have moderate symptoms and 57.8-97.8% weak or no symptoms.

Extended longitudinal study of uterine activity among low-risk women.

Eighty-nine black women without major medical risks for preterm labor participated in this longitudinal, prospective study for the evaluation of usual prelabor uterine activity and for the assessment of how gestational age, time of day, maternal weight, age, and parity affected contraction frequency. Participants wore an ambulatory tocodynamometer for 72 consecutive hours at three points in gestation during the second and early third trimesters while engaged in usual home and work activity. Data obtained from the 81 women with uncomplicated term pregnancies demonstrated a significant increase in contraction frequency with advancing gestational age between 22 and 33 weeks. After 26 weeks, significantly more uterine activity occurred at night. Perhaps because of detection difficulties, contraction frequency was inversely related to maternal weight in women weighing greater than 112% ideal weight. Maternal age and parity did not affect contraction frequency. Contraction characteristics of eight women experiencing preterm labor or medically indicated preterm delivery are described.
