Sacral bladder denervation for treatment of detrusor hyperreflexia and autonomic dysreflexia.

OBJECTIVES: Detrusor hyperreflexia after spinal cord injury may cause urinary incontinence and chronic renal failure. In patients refractory to conservative treatment and not eligible for ventral sacral root stimulation for electrically induced micturition, we investigated the therapeutic value of sacral bladder denervation as a stand-alone procedure. METHODS: Nine patients (8 men and 1 woman) between 21 and 58 years old (mean 30.2) with traumatic suprasacral spinal cord lesions underwent sacral bladder denervation for treatment of detrusor hyperreflexia and/or autonomic dysreflexia. RESULTS: Detrusor hyperreflexia and autonomic dysreflexia were eliminated in all cases. Bladder capacity increased from 177.8 +/- 39.6 to 668.9 +/- 64.3 mL; intravesical pressure decreased from 89.3 +/- 19.1 to 20.2 +/- 2.7 cm H(2)O. For facilitating clean intermittent catheterization (CIC), 4 patients received a continent vesicostomy in a second-stage procedure; one of them in combination with bladder augmentation. Four patients empty their bladder by way of urethral CIC. One completely tetraplegic patient has an indwelling urethral catheter. In the 5 patients with autonomic dysreflexia, the systolic blood pressure was lowered from 196 +/- 16.9 to 124 +/- 9.3 mm Hg and the diastolic blood pressure from 114 +/- 5.1 to 76 +/- 5.1. The annual frequency of urinary tract infections decreased from 9 +/- 1.2 to 1.8 +/- 0.7. In all patients, renal function remained stable. CONCLUSIONS: In selected patients with detrusor hyperreflexia and/or autonomic dysreflexia, sacral bladder denervation is a valuable treatment option. It is only moderately invasive in nature, requires neither sophisticated nor expensive medical equipment, and is an attractive alternative to urinary diversion using intestinal segments.

Orthotopic bladder augmentation and substitution.

Orthotopic bladder augmentation or substitution using intestinal segments has become a standard procedure for many disorders that cause a loss of functional or anatomical bladder capacity. From the technical point of view, reservoir configuration by detubularizing the intestinal segments is the general practice. Various techniques exist, depending which types of segments and which techniques of ureteral implantation are used. Common problems include urinary incontinence, retention, metabolic disorders, and the possibility of secondary malignancies. As a result, research has been conducted into utilizing tissues other than intestine for bladder augmentation or substitution.

Surgery for local recurrence or distant metastases in patients aged 75 years or older.

Between 1982 and 1997, a total of 105 patients aged 75 years or older (median age 78 years) underwent surgical treatment for recurrent solid tumours. The most frequent primary tumours were melanoma, colorectal carcinoma and breast cancer. Sixty-one patients had complete removal of recurrent tumour. Post-operative mortality was 3.8% (four of 105 patients). The median hospital stay was 16 days and the post-operative hospital stay was 10 days. At a median follow-up of 57 months, 77 patients had died. Twenty one patients died of causes unrelated to the tumour. The overall survival of 105 patients was 35% at 3 years and 27% at 5 years. Following R0 resection, 5-year survival was 43%, (n = 61) and in the absence of post-operative complications even reached 50% (n = 47). Survival correlated with completeness of tumour resection (P<0.0001) and post-operative complications (P=0.021). No significant correlation could be established between survival and age, ASA score, blood replacement, primary tumour location or sex. Elderly patients presenting with recurrent tumour should be evaluated for surgical resection. If tumour removal is complete and post-operative complications are avoided, a 5-year survival rate of over 40% may be expected.
