ABSTRACT
Five cases of acute urinary obstruction during pregnancy are presented. A complete urodynamic workup, including pressure-flow studies showed high micturitional pressures with little or no flow, with at least 60% residual urine. Filling cystometry, urethral profilometry (static and dynamic), pelvic electromyography were normal. Two cases were due to uterine pelvic incarceration. One of these cases happened very early during pregnancy, because of extensive fibroids. Any cause of abnormal uterine enlargement can lead to early obstruction. Three cases were associated with paraurethral abscess (skenitis in 2 cases, urethral diverticulum in 1). Manual reduction in case of pelvic incarceration or surgical draining and antibiotic therapy in case of abscess were effective in all cases. Immediate catheterization is possible and indicated as soon as urinary obstruction is diagnosed. This prevents neuromuscular dysfunction due to excessive bladder distention. The transurethral catheter might work as a stent, and periurethral surgical drainage is probably safer with a catheter in place. Suprapubic catheterization is probably less useful in this respect. An indwelling catheter removes any urgency in treatment. Voiding difficulties can persist for some days after surgical treatment. Urodynamic testing performed in all indicated acute micturitional obstruction. Anyway, it added little to the clinical understanding of the problem, which was obvious, and the Authors feel that extensive urodynamic testing should be limited to cases presenting with a complex preexisting dysfunction or performed after treatment if symptoms do not disappear completely. All clinically doubtful cases should likewise be investigated. If periurethral abscess or incarceration are evident, simple evaluation of residual urine percentage should be sufficient in establishing the diagnosis.
