Der Einsatz von Natrium-Chondroitinsulfat bei der Behandlung der „Überaktiven Blase”

OBJECTIVE

It is not always possible to clearly differentiate the symptoms of overactive bladder and interstitial cystitis. A prospective randomized study was performed to determine whether instillation of sodium chondroitin sulphate for treatment of interstitial cystitis is also effective in treating overactive bladder. The expected benefit of this therapeutic approach in overactive bladder is based on the assumption that the glycosaminoglycan layer may be damaged in overactive bladder as well.

MATERIAL AND METHODS

Patients with chronic overactive bladder were randomized to one of two study groups each including 41 patients. Group A was treated with an anticholinergic agent (tolterodine), group B with sodium chondroitin sulphate (Uropol S). The diagnosis was established on the basis of a gynecologic examination and history, urodynamic testing, introital ultrasound, and cystoscopy. Patients were treated for 12 months.

RESULTS

An improvement of symptoms was reported by 15/35 (43 %) of the patients in group A (p = 0.000) as compared with 23/32 (72 %) of the patients in group B. The subjective outcome was corroborated by means of urodynamic testing, number of pads used, voiding frequency, and nycturia (voiding diary). Quality of life increased significantly in both groups in the course of treatment but there was no significant difference between both groups.

CONCLUSION

The results of the study presented here suggest that restoring the glycosaminoglycan layer also improves or cures the symptoms in patients with overactive bladder. Patients clearly benefit from instillation of sodium chondroitin sulphate. These results must be confirmed in larger studies before a wider use of this therapeutic option can be recommended.

Management bei postoperativ diagnostizierter intravesikaler TVT-Bandlage anhand zweier Kasuistiken

Recurrent urinary tract infections and symptoms of a hyperactive bladder in women having undergone a TVT (tension-free vaginal tape) procedure may be due to intravesical position of the tape. Urogenital ultrasound can provide early preliminary diagnostic evidence, which can then be confirmed by subsequent urethrocystoscopy. Minimally invasive revision can be achieved by transurethral resection of the intravesical TVT portions. Tape portions near the wall can be removed after stretching of the tape with grasping forceps inserted through a suprapubically placed trocar. This simple procedure can spare the patient a more extensive repeat operation for removal of the intravesical TVT that may even require a combined abdominovaginal approach.

Vaginale Revision bei Irritation des N. obturatorius nach Burch-Kolposuspension

Irritation of the obturator-nerve within colposuspension is a possible complication because of topographic proximity between obturator-nerve and operating-field. The main symptoms are weakness of the adductor muscles, sensory disturbance of thigh till paralysis and pain in the operating- field early after surgery. Too lateral fixing of the sutures in the pectineal ligament above the obturator-channel can cause compression of the obturator-nerve. Precocious intervention is a precondition for complete remission of symptoms, retropubic revise of surgery is evident. The method outlined here describes vaginal access for re-surgery with lateral colpotomy and dissection of the proximal colposuspension s suture. In this way a recurrent laparotomy with additional trauma of the operating-field can be avoided. In the case described here, this method led to the patients complete remission.

Pathogenesis of urethral funneling in women with stress urinary incontinence assessed by introital ultrasound

OBJECTIVE

The incidence of urethral funneling (UF) seen in women with stress urinary incontinence (SUI) during straining is reported to range from 18.6% to 97.4%. Its morphologic basis is unknown. The aim of the present study was to determine whether SUI patients with and without UF differ in terms of history, urodynamic results and magnetic resonance imaging (MRI) findings.

PATIENTS AND METHODS

Fifty-four women (mean age 52 +/- 11 years) with a history of SUI confirmed by clinical and urodynamic findings were included in the study. UF was demonstrated by introital ultrasound performed at a bladder filling volume of 300 mL during maximal straining. MRI for assessment of the urethra, levator ani muscle and endopelvic fascia was performed using axial proton-density-weighted sequences.

RESULTS

UF was demonstrated by introital ultrasound in 59% of the patients with SUI (Group 1) and was absent in 41% (Group 2). There were no differences between the two groups in mean age (P = 0.208), the incidence of mild prolapse of the anterior vaginal wall (Aa, Ba; stage I; P = 0.741), and urodynamic parameters (urethral closure pressure at rest; P = 0.507). The percentages of nulliparous and parous women were 22% and 78% in Group 1 and 54% and 46% in Group 2 (P = 0.013). The two groups did not differ in the MRI demonstration of morphologic defects of the urethra, levator ani muscle and endopelvic fascia or of combined defects.

CONCLUSIONS

The results of the present study did not elucidate the pathogenesis of UF. The demonstration of UF crucially depends on the examination technique employed.

Transvaginaler Verschluss einer nach Re-Sectio caesarea aufgetretenen vesico-uterinen Fistel Typ I (Jozwik)

The development of a vesico-uterine fistula is a problem which occurs with an increasing number of caesarean sections. The main symptoms are permanent urinary incontinence, cyclic hematuria ("menouria") and amenorrhoea. In only 5 % of cases, spontaneous closure with bladder catheterization over weeks and hormonal management is possible, most of the time a surgical procedure is the definitive treatment. Until now, the resection of this kind of fistula was performed using a transabdominal approach most of the time. Our procedure describes a surgical repair using a transvaginal approach by exciding the fistula out of the bladder and uterus with primary closure. In this way, a recurrent laparotomy with all known associated risks could be avoided. However, after definitive treatment of the fistula, a new pregnancy should be delivered by performing a caesarean section. In this way, a rupture of the uterus during delivery could be prevented.
