Solifenacin is effective and well tolerated in patients with neurogenic detrusor overactivity: Results from the double-blind, randomized, active- and placebo-controlled SONIC urodynamic study

AIMS

To investigate the effect on urodynamics of 4 weeks treatment with solifenacin succinate in patients with neurogenic detrusor overactivity (NDO) due to multiple sclerosis (MS) or spinal cord injury (SCI).

METHODS

SONIC was a prospective, multicenter, double-blind, phase 3b/4 study investigating the efficacy and safety of solifenacin 10 mg in patients with NDO due to MS or SCI. Patients (n = 189) were randomized to placebo or active treatment (solifenacin 5 mg, 10 mg or oxybutynin hydrochloride 15 mg) for 4 weeks, after a 2-week, single-blind, placebo run-in period. The primary endpoint was change in maximum cystometric capacity (MCC) from baseline to end of treatment. The primary analysis compared solifenacin 10 mg versus placebo; all other comparisons were considered secondary. Secondary endpoints included changes in urodynamic parameters, patient-reported outcomes, and safety assessments.

RESULTS

In the primary analysis, solifenacin 10 mg significantly improved mean change from baseline MCC versus placebo (P < 0.001) and was associated with improvements in bladder volume at first contraction and at first leak as well as detrusor pressure at first leak. Similar results were obtained for oxybutynin versus placebo. Patient perception of bladder condition significantly improved with solifenacin 10 mg versus placebo (P = 0.041). There was a clear improvement in quality of life (QoL) in the solifenacin arms versus placebo. The overall incidence of adverse events was low.

CONCLUSIONS

In patients with NDO due to MS and SCI, 4 weeks of treatment with solifenacin 10 mg improved urodynamic variables and QoL versus placebo and was well tolerated. Neurourol. Urodynam. 36:414-421, 2017. © 2015 Wiley Periodicals, Inc.

Tumors of the rectum and anus

Within a ten year period we have performed 433 radical operations on the rectum. An anterior resection of rectum was done in 110 cases, low anterior resection in 60 patients, very low anterior resection was done by stapler in 32 patients and was sewn by hand in 10 patients. Colo-anal anastomoses were performed 86 times and abdominoperineal amputation of rectum sec. Miles 20 times. Local transsphincteric procedures were used 14 times. In 12 patients the colo-anal anastomosis was performed either for recurrence of tumor or after a Hartmann's procedure. In the carcinoma of the lower half of the rectum there is still an unsolved question: whether to perform a low or a very deep low anastomosis or whether an extirpation of rectum with sparing the sphincters and sewing a colo-anal anastomosis is more beneficial. In the years 1980-1995 we treated surgically 64 patients with a tumor in anal area. All patient underwent preoperative radio- and chemotherapy. In our group adenocarcinoma was demonstrated in 6 patients, squamous carcinoma in 48 patients and squamous cells of the carcinoma in situ in 10 patients.

[Pitfalls of deep pelvic anastomoses in rectal carcinoma]

Authors analyse a group of patients operated for colorectal carcinoma in their hospital during ten-years period 1982-1991. 421 patients were operated for ca recti, in more as 65% of cases the sphincter saving operation was preferred. The used method was elaborated by Hojo and Kaso from Japan. The contraindication of sphincter, and insufficiency of sphincter, objectively rectomanometrically detectable. The resection of urinary bladder was contemporary performed in 15 patients, the hysterectomy with adnexotomy in 8 patients, the vaginal resection in 5 cases and the resection of small intestine in 8 cases. The resection of os sacrum to S 3 was performed in 3 patients. The radical resection with establishment of the deep pelvic anastomosis is burdened by certain number of early and delayed complications, too. Authors analyse its causes, possible corrections, but also its prevention.

Simple flap valve for continent urinary diversion

OBJECTIVE

To provide a stable continence mechanism in patients with urinary diversion by creating a flap valve from the ileal wedge, sutured into the grooves of the reservoir mucosa.

PATIENTS AND METHODS

The valve's efficacy and stability were confirmed previously in an experimental study using five dogs. The valve was used in 22 patients with ileocaecal pouches and as a continence mechanism for cystostomy in two paraplegic women.

RESULTS

Continence was achieved in all but two patients. In these exceptions the valve was found to be abnormally short (only 2 cm). Re-operation restored one patient to continence but the second patient refused further surgery. There were no problems with either catheterization of the valve or with epithelialization of the serosal surface of the valve.

CONCLUSION

The valve is easy to construct and requires only a small intestinal segment; it has long-term mechanical and functional stability and can be easily catheterized. The valve provides continence even with increasing reservoir content and will accept a large catheter, which seems to be important in preventing lithiasis.

Surgical treatment of the atonic bladder ("vesical cap")

As demonstrated in animal experiments and in five patients with atonic bladders, "vesical cap" surgery causally solves detrusor impairment by functionally reinforcing it with a vital muscle layer from an ileal seromuscular flap. All other genuine components of the bladder are kept intact, which is very beneficial for bladder function.
