11/87. Anterior urethral valves--a rare cause of urethral obstruction.Anterior urethral valves is a very rare congenital anomaly of the anterior urethra. It produces symptoms of varied intensity with the most severe ones leading to Urosepsis and renal failure (similar to as in posterior urethral valves) to the milder ones which may not produce any obstruction at all. However unlike the Posterior urethral valves this anomaly has milder and reversible sequelae in majority of the cases. The clinical presentation is mainly in the form of obstructed stream of urine and UTI and the diagnosis depends essentially on Micturating Cystographic studies and on the awareness and a high level of suspicion of its existence among Paediatricians and general practitioners.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |
12/87. Simultaneous upper and lower urinary tract obstruction associated with severe genital prolapse: diagnosis and evaluation with magnetic resonance imaging.Genital prolapse causing both urethral and ureteral obstruction is an infrequent occurrence, especially in the absence of uterine prolapse. We report on a patient with massive genital prolapse causing both urethral and ureteral obstruction in whom magnetic resonance imaging demonstrated the level of obstructive uropathy and, after surgical repair of the prolapse, confirmed restoration of the normal pelvic and upper urinary tract anatomy.- - - - - - - - - - ranking = 1.2keywords = obstruction (Clic here for more details about this article) |
13/87. Treatment of a complete lower urinary tract obstruction secondary to an expandable foam sealant.We present a unique case of an iatrogenic complete lower urinary tract obstruction with an expandable foam sealant. A 41-year-old man presented in urinary retention 36 hours after self-injecting his urethra with the foam sealant, which could be palpated throughout his entire urethra. The sealant was removed from the distal urethra in numerous fragments with a hemostat and cystoscopically. A perfect mold of the bladder and prostatic urethra were removed by suprapubic cystotomy. cystoscopy 2 months later demonstrated a mild bulbar urethral stricture, but normal bladder mucosa. The cystoscopy at 6 months was normal.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |
14/87. Botulinum toxin urethral sphincter injection resolves urinary retention after pubovaginal sling operation.The management of prolonged urinary retention following pubovaginal sling surgery typically involves transvaginal urethrolysis for anatomical urethral obstruction. Brubaker [1] recently reported on urethral sphincter abnormalities as a cause of postoperative urinary retention following either Burch suspension or pubovaginal sling procedure. We report a case of functional urethral obstruction and detrusor acontractility following pubovaginal sling surgery that was successfully treated by botulinum A toxin urethral sphincter injection.- - - - - - - - - - ranking = 0.4keywords = obstruction (Clic here for more details about this article) |
15/87. Possible maternal inheritance of a common obstructive urinary tract anomaly. Report of a case of a woman with multiple urinary tract infections and two sons with posterior urethral valves.BACKGROUND: Posterior urethral valves (PUVs) are the most common cause of lower urinary tract obstruction in boys. Several prior reports have described PUV in siblings and twins, often with a variable phenotype. CASE: PUVs were found in two brothers. The first child had developmental delay, while the second had a branchial cleft cyst and an anteriorly rotated right ear. The children's mother had a history of numerous urinary tract infections of unknown etiology. CONCLUSION: Though most cases of PUV appear to be sporadic, there are reports that suggest a partial genetic etiology, as our case suggests.- - - - - - - - - - ranking = 0.2keywords = obstruction (Clic here for more details about this article) |
16/87. phimosis as a cause of the prune belly syndrome: comparison to a more common pattern of proximal penile urethra obstruction.The pathogenesis of the prune belly syndrome (PBS) remains controversial, but two theories predominate. The first theory supports an obstructive phenomenon early in gestation leading to irreversible damage to the genitourinary tract and abdominal wall. The second theory suggests mesodermal injury between the 6th and 10th weeks of gestation as the primary abnormality. This paper reports of two fetuses with the PBS phenotype that were examined postmortem at our institution. Thorough examination of the lower urinary tract allowed demonstration of anatomic obstruction of the urethra in both cases. One case illustrated a relatively common pattern of proximal penile urethral obstruction, a flap-like obstruction between the prostatic and penile urethra. The other case provided what we believe to be the first description of PBS caused by severe phimosis.- - - - - - - - - - ranking = 1.4keywords = obstruction (Clic here for more details about this article) |
17/87. Obstructive ARF caused by an inflammatory abdominal aortic aneurysm.Inflammatory abdominal aortic aneurysms are rare entities characterized by dense fibrosis typically enveloping the aortic wall and adjacent structures with distinctive clinical features that differentiate them from typical atherosclerotic aneurysms. The inflammatory process can involve the renal excretory pathways, causing ureteral obstruction in 20% of cases. The authors report 2 cases of complete obstructive anuria secondary to inflammatory aneurysms and discuss the most appropriate management for these situations of hydronephrosis. Surgical repair of the aneurysm usually leads to regression of the inflammatory reaction.- - - - - - - - - - ranking = 0.2keywords = obstruction (Clic here for more details about this article) |
18/87. Penile urethral obstruction in a subject with spinal cord injury.STUDY DESIGN: Single case report. OBJECTIVE: To report a case of urethral obstruction because of calculus in a subject with spinal cord injury (SCI). SETTING: Bangalore, india. CASE REPORT: A 25-year-old man sustained complete SCI at C(6) level following a road traffic accident. After 14 months, while on self-intermittent catheterization he noticed difficulty in introducing catheter and acute retention of urine. X-ray examination revealed a calculus in the penile urethra at the level of the glans penis. CONCLUSION: Impaction of calculi in penile urethra, although rare, can manifest with acute painless urinary retention in patients with SCI.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |

20/87. Anterior urethral valves and diverticula.Obstructive lesions of the anterior urethra (valves, diverticula) are rare and can be difficult to diagnose. One recent case led us to review existing international reports; there are case histories for 260 patients over a 20-year period. The anatomical interpretation of these lesions is far from being unequivocal but many authors clearly distinguish between valves and diverticula, the basic difference being in the contiguity between the anomaly and the corpus spongiosum. Where the clinical presentation depends on age, the diagnosis depends essentially on voiding cysto-urethrography, which must image the whole urethra. Generally, the treatment for valves is simple, consisting of endoscopic resection. For diverticula it is not always necessary or desirable to remove the diverticulum; if there is a well-formed distal obstructing lip, removing it may be enough to cure the obstruction.- - - - - - - - - - ranking = 0.2keywords = obstruction (Clic here for more details about this article) |
