Fifty consecutive female patients with genuine urinary stress incontinence were randomized either to surgery or to a pelvic floor training program. The operative procedure was chosen according to the type of bladder suspension defect on micturition cystourethrography. The training program was given 5 times in weekly lessons and the patients were guided by trained physiotherapists. Surgery was superior to the pelvic floor training program both subjectively and objectively. However, a significant improvement was found following the training program. Forty-two percent were satisfied with the outcome of the training and did not want operation. We find physiotherapist-guided pelvic floor exercise a realistic alternative to surgery in patients with mild degrees of stress incontinence. Also patients with residual symptoms after surgery are candidates for pelvic floor training.

Voiding colpo-cysto-urethrography was performed in 52 consecutive female patients with genuine urinary stress incontinence before treatment and in 50 of the patients after treatment. The patients were randomized to either pelvic floor training or surgery. Surgery included a colposuspension operation in patients with an anterior suspension defect and a vaginal repair in patients with a posterior suspension defect. All pre-and posttreatment examinations were reevaluated blindly by one observer 4 to 6 years later. The pretreatment radiologic reevaluation was in agreement with the original classification in 79 per cent and not in agreement in 21 per cent. Pelvic floor training did not change the degree of suspension defect systematically. The effect of squeezing was significantly improved following pelvic floor training. A colposuspension gave rise to a typical radiologic configuration of the bladder and urethra. A vaginal repair was not detectable radiologically and it did not correct a posterior descent. The degree of descent and the degree of incontinence were not correlated and it was not possible radiologically to distinguish treatment failures from treatment success.

Background: To evaluate low-field magnetic resonance imaging (MRI) in detecting therapeutic response in active Crohn's disease during treatment with systemic steroids. Methods: Eight patients with active Crohn's disease were examined before and during treatment with systemic steroids (1 mg/kg/day) using low-field MRI (0.1 T) in transverse and coronal planes before and after an intravenously administered bolus of gadodiamide. Five healthy persons were once examined in the same way. MRI images were evaluated without knowledge of diagnosis, treatment, or findings of endoscopy, conventional radiography, and surgery. Proximal and mid small bowel, terminal ileum, right-sided colon, transverse colon, and left-sided colon were evaluated separately. Results: Statistically significant differences were shown for both signal intensity on T2-(SI T2 ) and increment in signal intensity on T1-weighted images after contrast (%SI T1 ) when comparing diseased bowel segments with both nondiseased bowel segments (SI T2 : p ϭ 0.0001; %SI T1 : p ϭ 0.0009) and segments from the control group (SI T2 : p Ͻ 0.00005; %SI T1 : p Ͻ 0.00005). In 53 of 56 bowel segments evaluated (95%), agreement was found between findings by MRI, conventional radiography, endoscopy and/or surgery regarding disease extension. Extension was underestimated in two patients. All bowel segments in the control subjects were evaluated to be normal on MRI. Significant correlation was found between both SI T1 (p Ͻ 0.0025) and %SIT1 (p Ͻ 0.025) versus endoscopic activity gradings. During treatment, significant decrements of both SI T2 (p Ͻ 0.00005), %SI T1

In a prospective, blinded study we investigated 30 patients with Crohn's disease (CD) and 27 normal controls by means of dynamic grey-scale ultrasound scan. Within a few weeks the patients were also examined by radiography of the small bowel. Of the 30 patients, 21 had CD lesion of the small bowel as judged by radiography. A target lesion at the ultrasound scan indicating thickened bowel wall was seen in 15 CD patients, of which 14 showed radiographic signs of CD in the ileum and/or right side of the large bowel, whereas one had normal radiographic findings. Seven patients out of 15 without sonographic changes had radiographic signs of CD. The patients with discrepancy between the two examinations could not be clinically characterized as an entity. None of the 27 normal controls showed signs of intestinal disease at the ultrasound examination. We conclude that dynamic grey-scale ultrasound examination is a new tool in depicting the CD lesion, but it does not seem to be able to replace the radiographic examination. However, it may find a place in the follow-up study of patients with known CD, thereby avoiding repeated radiographic examinations. Furthermore, the possibility of diagnosing abscesses and fistulae by sonography is well known and has relevance in CD.
