A 4-hour observation period has been used in infants to investigate suspected bladder dysfunction. The aim of the present study was to extend the usefulness of this protocol by establishing reference values for voiding frequency, intervals, volumes, and residual urine in healthy newborns. The study included 51 healthy newborns, 26 girls and 25 boys, aged 3 to 14 days. During a 4-hour period, all micturitions and residuals were recorded as well as feeding, sleeping, crying, and defecations. The observation was completed with the child undressed to observe the urinary stream during one void. Different provocation tests were tried to induce urinary leakage. All newborns voided with a stream, about once per hour, with a median volume of 23 mL. For each voiding parameter, there was a large inter- and intra-individual variability. Double voidings were common as well as sizable residual volumes. The diuresis was about six times higher than in healthy school children. The healthy newborns did not leak during provocation tests such as manual compression of the bladder. Neurourol. Urodynam. 19:177-184, 2000.
Gynecologists have traditionally evaluated rectocele repair by its effect on vaginal function; coloproctologists have traditionally evaluated its effect on bowel function. Hence different operative criteria and surgical techniques have arisen, but with very little prospective, objective evaluation. The purpose of this review is to describe the surgical techniques used to repair the rectocele and the most common investigations used during its evaluation. Anorectal investigations identify concomitant pathology, may explain pathophysiology, provide objective outcome criteria and attempt to predict the patients that will most benefit from surgery. However, because of the complex neuromuscular, physiological and mechanical interactions that contribute to impaired rectal emptying, their usefulness in improving functional outcome has been limited. Many patients experience improvement, but still are left with some symptoms of impaired defecation despite anatomic correction.
BACKGROUND: The study was designed to investigate the clinical presentation and laboratory findings of anterior rectal mucosal prolapse (ARMP) and to assess the results of two therapeutic modalities. METHODS: Some 162 women with ARMP were assessed clinically and by defaecography and rectoanal manometry before and 1 year after one or two sessions of submucosal sclerotherapy or, in the case of recurrence, after transanal excision of the prolapsing mucosa. RESULTS: Almost all patients reported a combination of symptoms suggesting obstructive defaecation. At defaecography anterior rectocele and excessive perineal descent at straining were present in 78 and 72 per cent respectively. The size of coexisting anterior rectocele and the extent of perineal descent were significantly related to the duration of the disease (P< 0.001). One or, in the event of recurrence, two sessions of sclerotherapy led to an overall success rate of 51 per cent. Improvement after sclerotherapy was associated with partial recovery of anal tone and improvement of anal sampling and rectal sensation. Failure of sclerotherapy was related to rectocele of larger size (P< 0.001) and a longer perineal descent at straining (P< 0.001) than in patients with a successful outcome. Excision of the prolapsing mucosa resulted in symptomatic improvement in 42 of 47 patients and was associated with significant improvement of the defaecographic and manometric findings. CONCLUSION: ARMP is usually associated with anterior rectocele and excessive perineal descent. Submucosal sclerotherapy is successful in half of the cases, but only in the presence of a rather small anterior rectocele and short perineal descent. Failures after sclerotherapy can be treated by transanal excision of the prolapsing mucosa.
