Functional detrusor myoplasty for bladder acontractility: long-term results

Area of Science:

• Urology
• Surgical Innovation
• Neurogenic Bladder Management

Background:

• Lower motor neuron lesions can cause bladder acontractility, necessitating lifelong clean intermittent catheterization (CIC).
• Existing treatment options for such cases are limited, often leaving CIC as the only alternative.
• Investigating novel surgical approaches is crucial for improving patient quality of life.

Purpose of the Study:

• To evaluate the long-term efficacy of latissimus dorsi detrusor myoplasty in patients with bladder acontractility.
• To assess the potential of this procedure as an alternative to CIC.
• To analyze urodynamic parameters and clinical outcomes post-myoplasty.

Main Methods:

• A multicenter study involving 24 patients (median age 39) with neurogenic bladder acontractility requiring CIC.
• Patients underwent latissimus dorsi detrusor myoplasty between 2001 and 2008.
• Follow-up included urodynamics, post-void residual urine volume measurement, and bladder contractility index calculation over a median of 46 months.

Main Results:

• 71% of patients achieved complete spontaneous voiding with a mean post-void residual urine volume of 25 ml.
• Mean bladder contractility index significantly increased from 20.1 to 176.2 (p <0.001).
• 91% of patients experienced cessation of recurrent urinary tract infections; no chronic pain or vesicoureteral reflux was reported.

Conclusions:

• Latissimus dorsi detrusor myoplasty is an effective treatment for select patients with neurogenic bladder acontractility.
• The procedure offers a promising alternative to lifelong CIC, improving bladder function and reducing infection rates.
• Further research can explore patient selection criteria and long-term outcomes.
