1/72. Use of rigid hysteroscope for extraction of foreign bodies embedded in lower urinary tract.

    PURPOSE: To introduce the use of the 20F rigid hysteroscope in urologic procedures. MATERIALS AND methods: The 20F hysteroscope was used to remove deeply embedded foreign bodies from the lower urinary tract of three patients in whom previous attempts with standard cystoscopic equipment were unsuccessful. RESULTS: In all three cases, the hysteroscope easily passed into the urethra and with the use of rigid instruments was able to remove the foreign bodies without complication. CONCLUSION: Situations may arise when the removal of embedded foreign bodies is not possible with standard cystoscopic equipment. The hysteroscope, which is available in most operating rooms, was able to extirpate even deeply embedded foreign bodies.

2/72. Postpartum uterine retroversion causing bladder outflow obstruction: cure by laparoscopic ventrosuspension.

    A case of chronic urinary retention due to bladder outflow obstruction presenting at 7 months postpartum, following a history of early puerperal voiding difficulties, is outlined. The cause was found to be a markedly retroverted uterus obstructing the urethra. Laparoscopic ventrosuspension was performed, converting preoperative urinary residuals of over 400 ml to zero postoperatively.

3/72. Inferior vena cava compression due to massive hydronephrosis from bladder outlet obstruction.

    A 71-year-old man presented with acute urinary retention due to benign prostatic hyperplasia and was found to have computed tomography-documented mechanical obstruction of the inferior vena cava (IVC) due to massive hydronephrosis. Obstruction of IVC flow promptly resolved after bladder decompression.

4/72. Cystic rectal duplication: a rare cause of neonatal bladder-outlet obstruction and hydronephrosis.

    A case of cystic rectal duplication (RD) is presented. A 7-day-old female was admitted with acute urinary retention, voiding difficulty, and abdominal distention since she was 4 days of age. Ultrasound and abdominal computed tomography (CT) demonstrated a huge, cystic mass in the pelvis and abdomen that resulted in acute urinary retention and bilateral hydronephrosis. CT-guided drainage of the lesion followed by transabdominal surgical excision resulted in a cure. Pathologic examination demonstrated a RD lined by respiratory epithelium.

5/72. Left multicystic dysplastic kidney with contralateral ectopic kidney and ureterovesicle junction obstruction.

    multicystic dysplastic kidney (MCDK) represents the most common cause of abdominal mass in the neonatal period. It is usually combined with contralateral genitourinary tract anomaly. Because the multicystic dysplastic kidney is usually dysfunctional, it is important to evaluate and monitor the remaining preserved function of the contralateral kidney regularly. The presence of severe obstructive lesion over contralateral kidney is often life-threatening. Prompt treatment should therefore be given as early as possible to preserve the remaining renal function. We here report one rare case of left MCDK with contralateral ectopic kidney and ureterovesicle junction (UVJ) obstruction. As the best as we know, this report is the first case report of MCDK with contralateral ectopic kidney and UVJ obstruction.

6/72. In utero intervention in a patient with prune-belly syndrome and severe urethral hypoplasia.

    Prenatal ultrasound scanning of a 20-year-old woman at 17 weeks of gestation revealed findings suggestive of bladder outlet obstruction, including bladder distension, dilated bilateral ureters, urinary ascites, and oligohydramnios. Vesicoamniotic shunts were placed with decompression of the bladder and correction of the amniotic fluid levels. Labor was induced at 36 weeks' gestation. At birth, the infant was noted to have prune-belly syndrome with severe urethral hypoplasia, a variant usually associated with a poor prognosis, necessitating vesicostomy for bladder drainage. We present a case of a patient with prune-belly syndrome and bladder outlet obstruction in whom early intervention resulted in an excellent outcome with preservation of renal and pulmonary function.

7/72. Ureteral pressure flow studies in difficult diagnostic problems.

    Before a ureteral operation is undertaken for dilated, non-refluxing ureters it is essential to determine whether obstruction is present, since an operation is unnecessary and can be hazardous if there is no obstruction or infection. Obstruction is most accurately diagnosed by perfusing the upper tract at a known flow rate and measuring the resulting pressure. This test was performed on 5 patients in whom there was doubt as to the presence of obstruction from the radiographic evidence. In 4 of the 5 patients low pressure was found, the obstruction was excluded and an operation was avoided. In the fifth patient the obstruction was confirmed and relieved. The pressure flow test is useful in the diagnosis or exclusion of obstruction in the upper urinary tract.

8/72. Bladder neck obstruction in the female.

    Bladder neck dysfunction is a rare cause of obstruction in women. The symptoms are nonspecific and diagnosis relies on video-urodynamic evaluation. In this case study, a woman presented with urinary retention, recurring urinary tract infections, and bilateral hydronephrosis, in whom video-urodynamics revealed bladder neck obstruction. Her clinical presentation, as well as the pertinent literature on the diagnosis and treatment of bladder neck obstruction in women, are reviewed.

9/72. Limb constriction as a complication of intra-uterine vesico-amniotic shunt: fetoscopic release.

    Complete fetal bladder outlet obstruction was first diagnosed in a fetus at 13.5 weeks. After sequential vesicocentesis had shown good renal function, a vesico-amniotic shunt was inserted at 17 weeks with a Rodeck catheter. The procedure was successful and amniotic fluid volume re-accumulated to normal levels. A detailed scan at 20 weeks showed that the distal free end of the catheter was wound round the left fetal thigh. As the fetus grew, there was progressive constriction of the fetal thigh by the catheter. By 29 weeks, Doppler blood flow changes to the left leg were apparent. Fetoscopic surgery was performed at 30 weeks to release the constriction. The catheter was divided successfully, but the divided end of the shunt subsequently retracted into the fetal abdomen, producing urinary ascites, bilateral hydroureter and hydronephrosis. The baby was delivered at 31.5 weeks in good condition. Endoscopic resection of anterior and posterior urethral valves was performed at 6 months of age. At 2 years, the child has normal renal function, growth parameters and developmental milestones. Mild indentation of the left thigh was still apparent, although there was no functional impairment.

10/72. Transurethral resection versus open surgery for leiomyoma of urinary bladder--a report of 2 cases.

    The authors describe two patients with leiomyoma of the bladder who presented with bladder outlet obstruction. The results of magnetic resonance imaging are presented and their management discussed. Complete resection was curative in both patients, by enucleation in the first case and by transurethral resection in the second.
