[Occurrence of athletic injuries among female elite athletic gymnasts].

A questionnaire investigation was undertaken among 18 female Nordic athletic gymnasts in the teams from their respective countries. The median occurrence of injury was three injuries per 1,000 hours (variation 0-7) with uniform distribution between acute and overexertion injuries. The percentage regional localization were: Upper limbs 24%, lower limbs 65% and trunk 11%. In the age group 18-21 years, the frequency of injury was 46% higher than that in the 14-17 year age group and gymnasts with the greatest duration of training had relatively low incidence of injuries (2.7 as compared with 5.2 injuries per 1,000 hours). Treatment consisted of visits to the general practitioner, casualty department and sport specialist or other specialist comprized 16%, 13% and 16% of all the therapeutic contacts. 5% of the injuries involved hospitalization and 50% were not treated by doctors.

Urethral strictures after transurethral bladder tumor resection.

The charts on 241 patients, consecutively undergoing a total of 2043 transurethral resections of bladder tumors and subsequent controls, were reviewed to find the incidence and possible causes of postoperative urethral stricture. The incidence of urethral stricture was 15% in males and 4% in females, but less than one-third were symptomatic. The strictures were found distally in the urethra in 83% of the patients and were treated with optical urethrotomy. Cumulated duration of postoperative catheterization was significantly longer and size of resectoscope used larger in patients with stricture. Repeated transurethral instrumentations may increase the risk of stricture development.

Significance of the extent of transurethral prostatic resection for postoperative complications.

The significance of the extent of transurethral prostatic resection for benign prostatic hypertrophy was evaluated as regards early and late postoperative complications in a prospective, randomized study. The two treatment groups were preoperatively comparable in age, incidence of urinary retention and estimated prostatic weight. In 83 cases the median weight of resected tissue was 18 (range 4-118) g, while in 84 cases the resection was less extensive--median weight 7 (1-40) g. No significant intergroup difference was found in incidence of bladder tamponade, bladder perforation, urinary tract infection or pneumonia. The blood transfusion need was greatest among the patients with complete transurethral adenomectomy of the prostate. Concerning late postoperative complications, the groups did not differ in incidence of urethral stricture, bladder neck contracture or reoperation for benign prostatic hypertrophy. Patients with preoperative urethral instrumentation had heightened risk of developing postoperative urethral stricture.

Initial experience with percutaneous nephrolithotomy: results, problems and complications.

Initial experience from 132 cases of percutaneous lithotripsy performed at three departments in Arhus County in 1984-85 is reviewed. Twenty patients were not offered a percutaneous operation during this period. In 12 cases the stone had to be removed by open operation. Another 12 cases were also regarded as failures due to important residual stones or fragments. Stone free kidneys were obtained in 86 cases (64%), whereas 22 (17%) had minor residual stones or fragments considered unimportant in relation to the present indications for operation. Stones 20 mm in diameter, and especially staghorn stones frequently gave failures. Minor complications were recorded in 29 patients and resulted in 7 open operations, mostly from the early part of the series. Five severe complications were seen. An old weak man died from late complications after bleeding. The four others were operated for pulmonary embolism (1 pt), late bleeding (traumatic aneurysm, 2 pt) and colonic perforation (1 pt). They all recovered.

Vesico-ureteral reflux in children.

A total of 126 children with 193 refluxing renal units were treated for vesico-ureteral reflux during the period 1966-74. The grading of the cases into mild, moderate and severe reflux revealed renal scarring in 5, 22 and 28% of the three groups. Conservative treatment was used in 10% of the patients, surgery on the urethra in 25%, and reimplantation of the ureter by the Politano-Leadbetter technique in the last two-thirds of the patients. Reflux was eliminated in 50% of the renal units treated conservatively, in 60% of renal units treated with surgery on the urethra, and in 86% of units treated with reimplantation. The overall results seemed to be better in mild than in moderate or severe reflux. The dilatation of the upper urinary tract returned to or approached normal in 85%. Of the children, 80% were without symptoms postoperatively, whereas urinary-tract infection persisted in 36%. The value of the grading of reflux is emphasised, and indications for treatment are discussed.

Compensatory renal hypertrophy. I. Following unilateral nephrectomy. An experimental study in dogs.

The compensatory renal hypertrophy and hyperfunction following unilateral nephrectomy have been studied in dogs over a two-year period. It was found that a sharp increase in function and volume of kidney tissue takes place during the first two weeks. CCr and volume of kidney tissue continue to increase reaching average values after two years of 88% and 92% respectively of those for two kidneys. CPAH and TmPAH remain almost stable at 65% and 57% respectively after an initial increase during the first two weeks. All values are expressed in percent of the function of two normal kidneys before unilateral nephrectomy. The filtration seems to be increasingly efficient and the functional integrity of the nephrons is preserved, although a glomerular predominance is encountered two years following unilateral nephrectomy.

Compensatory renal hypertrophy. II. During contralateral hydronephrosis. An experimental study in dogs.

Compensatory renal hypertrophy and hyperfunction during contralateral chronic hydronephrosis was investigated. It was found that graded impairment of the function in hydronephrotic kidneys causes proportional compensatory hypertrophy and hyperfunction in the contralateral normal kidney. The functional pattern both "per kidney" and "per nephron" was the same in the kidneys investigated here and in kidneys where contralateral nephrectomy had been performed, but whereas a decreased ability to concentrate the urine maximally and to reabsorb sodium was encountered in the latter, this could not be detected in this study. On the other hand, a decreased COSM in the diseased kidney did not stimulate a corresponding increase in the contralateral kidney as did unilateral nephrectomy. Adaptive and growth dependent changes in compensatory renal hypertrophy are discussed.
