Radiological and ultrasonographic imaging enables the objective determination of bladder neck position and movement in stress urinary incontinence. Postoperative results were evaluated in 60 patients after Burch colposuspension (29) or bladder neck suspension according to the Gittes (18) or Stamey (13) method. No differences in continence rates were noted 3 months postoperatively (Gittes 83%, Stamey 85% and Burch 93% of the patients). Late results were assessed by urodynamic evaluation and transvaginal ultrasonography. The largest decrease in continence rate was observed after the Gittes procedure (44% of the patients continent, mean followup 14.7 months), in comparison with the Stamey (69% continent after 34.6 months) and Burch (86% continent after 30.5 months) procedures. Urodynamic parameters showed no significant differences for the 3 groups. Transvaginal ultrasonography did not indicate a correlation between absolute resting or stress position of the bladder neck and continence. The main factor concerning continence was the rotation angle and descent of the bladder neck during stress. Our data indicate that transvaginal ultrasonography is a safe and reliable method to evaluate the postoperative outcome for stress urinary incontinence.
The immune reactivity of patients with strongly recurrent superficial bladder cancer was followed after combined intravesical and intradermal bacillus Calmette-Guérin (BCG) immunotherapy. All patients in this study were previously treated without success with intravesical chemotherapy. The BCG treatment regimen consisted of weekly administrations with BCG (RIVM) for six consecutive weeks, both intravesically and intradermally. In this study, sera and peripheral blood leukocytes (PBL) of patients were tested serially. Besides BCG-antigen-specific reactions, e.g. skin reactivity to purified protein derivatives of Mycobacterium tuberculosis (PPD), antibody formation and antigen stimulation of PBL in vitro, non-antigen-specific immune reactivities were also measured, e.g. mitogen response and spontaneous cytotoxic activity of PBL. In addition the antibody response to bladder carcinoma antigens and the cytotoxic activity of PBL for the bladder carcinoma cell line T24 and the natural-killer-sensitive K562 cell line were investigated. The results obtained from the various assays were evaluated for their prognostic value in relation to the length of the tumor-free interval after the BCG treatment. Because sera and PBL were only obtained during the first 6 months after the BCG treatment, the immune reactivity was compared to the clinical results at that same time. At 6 months after therapy 12 out of 40 BCG-treated patients were tumor-free whereas 28 out of 40 showed a recurrence. Skin reactivity to tuberculin PPD was measured in 40 patients during a period of 3-6 months after therapy. Of patients who showed a recurrence of the tumor within 6 months, 48% of them showed a transient response or developed no response at all to PPD. In the group of patients with a longer tumor-free period (n = 10), only one patient lost the response to tuberculin PPD. Although PBL of a limited number of patients were tested, it was observed that the cytotoxicity to the bladder carcinoma cell line T24, and the natural-killer-sensitive K562 cell line increased in a number of the patients (7 out of 14, and 9 out of 14 respectively). Reactivity of PBL to mitogens and subset distribution (ratio T-helper: T-suppressor/cytotoxic) were not influenced by the BCG treatment. Antibody response to mycobacterial antigen was detected in 9 out of 23 patients investigated. Of these 9 patients, 8 belonged to the group with a recurrence of the tumor within 6 months (n = 17). There was no correlation between the skin reactivity and the antibody response to tuberculin PPD.(ABSTRACT TRUNCATED AT 400 WORDS)
Ten adults with enuresis were treated by bladder transection. Urodynamic assessment was carried out before and after the operation. No significant urodynamic changes were recorded following transection. However, good results were obtained in 5 cases and improvement in 2.
In an open, randomized study, the effect of pefloxacin (400 mg b.i.d.) was compared with that of cefotaxime (1 g t.i.d.) in the treatment of complicated urinary tract infections. In total 87 patients entered the study under the clinical diagnosis of complicated urinary tract infection, of whom 49 were eligible for evaluation. Most isolates (90%) belonged to the family of Enterobacteriaceae. Isolates were eradicated from 96% (28/29) of patients treated with pefloxacin and 89% (16/18) of those receiving cefotaxime 48 h after the end of therapy. After one week a total of 92% (22/24) of patients treated with pefloxacin were culture negative, while in the group treated with cefotaxime a total of 82% (9/11) were culture negative. After four to six weeks, 68% (13/19) in the pefloxacin and 80% (8/10) in the cefotaxime study group showed a negative urine culture (difference non-significant; p greater than 0.5). Clinical cure at the end of treatment was 97% (30/31) in the pefloxacin group vs. 89% (16/18) in the cefotaxime group. Both groups showed similar relapse and reinfection rates at 48 h and one week after therapy. Adverse effects were mild and reversible for both drugs. It is concluded that pefloxacin is a safe and effective alternative for treatment of complicated urinary tract infection.
