Lazy bladder syndrome

Bauer (1992) grouped into primarily unstable bladder (small capacity, hypertonic bladders and detrusor hyperreflexia), infrequent voiding associated with large-capacity bladders (lazy bladder syndrome) and psychogenic nonneuropathic bladder (Hinman syndrome). 

Lazy bladder syndrome is the consequence of longstanding dysfunctional voiding. It results from detrusor decompensation. Abdominal pressure is mostly responsible for voiding. Large residual urine volume can be observed (N0rgaard et al. 1998). 

Hoebeke et al. (2001) in a publication about 1,000 videourodynamic studies in children with nonneurogenic bladder dysfunction found urge syndrome (overactive bladder or unstable bladder) in 58% (male female ratio 58 42), dysfunctional voiding (overactivity of the external urethral sphincter) in 32% (male female ratio 49 51) and lazy bladder in 4% (male female ratio 20 80). Furthermore, he found that the age distribution provided evidence against a dysfunction sequence as mentioned above.
