Urethral Obstruction


  • Their voiding cystograms, video-recorded cystoscopy and presenting signs were reviewed. RESULTS: Of the 39 boys assessed, a voiding cystogram and presenting signs were available in 36.[ncbi.nlm.nih.gov]
  • In three infants a gangrenous lesion at the distal part of the affected leg was found; in another three infants, necrotic tissue was noted in the stump of the affected leg. This type of lesion can be explained only on a vascular ischemic basis.[ncbi.nlm.nih.gov]
Wide Neck
  • All the stones were completely removed and a check Cystoscopy confirmed the wide neck urethral Diverticulum (Figure 3 ). Figure 2 Manual antegrade removal of urethra stones.[bmcurol.biomedcentral.com]
Bladder Neck Obstruction
  • The index cannot differentiate the site of obstruction as noted by the similar scores among men with BPH from those with bladder neck obstruction and urethral strictures.[ncbi.nlm.nih.gov]
  • Bladder neck obstruction in women: a real entity. J Urol 1984; 132: 294-298 11) Nitti VW, Tu LM, Gitlin J. Diagnosing bladder outlet obstruction in women. J Urol 1999; 161: 1535-1540 12) Groutz A, Blaivas JG, Chaikin DC.[minds.jcqhc.or.jp]
  • Bladder neck obstruction. Congenital urethral valves. Pinhole meatus. Neurogenic bladder. Functional failure due to denervation (eg, following spinal trauma, multiple sclerosis).[patient.info]
Urinary Hesitancy
  • hesitancy) Slow, uneven urine flow, at times being unable to urinate Straining to urinate Urinary tract infection Waking up at night to urinate ( nocturia ) Your health care provider will ask about your symptoms and medical history.[medlineplus.gov]
  • Chronic lower tract obstruction Usual signs and symptoms include: Urinary hesitancy. Narrow and weak urine stream. Dribbling at end of micturition. Feeling of incompletely emptied bladder.[patient.info]
  • Abstract Abdominal muscle deficiency, urinary tract abnormalities, and cryptorchidism are the three major features of the prune-belly syndrome, also referred to as triad syndrome or Eagle-Barrett syndrome.[ncbi.nlm.nih.gov]
  • Anuria suggests bilateral complete obstruction. Chronic upper tract obstruction Presents with flank or abdominal pain and/or chronic kidney disease. Polyuria may be a feature.[patient.info]


  • This modality provides the same information as IVP without depending on renal function and can be used when the risks of IVP are considered too great Ultrasonography – This is the procedure of choice for determining the presence of hydronephrosis See Workup[emedicine.medscape.com]
  • We also evaluated the postoperative postvoid residual (PVR) and presence of pyuria, and reviewed postoperative complications and unassisted urination ability. RESULTS: We found a positive correlation between prostatic urethral length and TPV.[ncbi.nlm.nih.gov]


  • Abstract Voiding dysfunction after surgical treatment of stress incontinence may occur as a result of urethral obstruction secondary to hyperelevation of the bladder neck.[ncbi.nlm.nih.gov]


  • Fetal urinary electrolyte and beta2-microglobulin concentrations at 14 weeks' gestation indicated a poor renal prognosis. The pregnancy was therefore terminated.[ncbi.nlm.nih.gov]
  • Does prenatal diagnosis influence prognosis? Br J Urol 1993;72:830–833. Article / Publication Details First-Page Preview[karger.com]
  • Prognosis: Severe: high perinatal mortality due to pulmonary hypoplasia secondary to severe oligohydramnios. Even in those that survive, about 30% develop renal failure necessitating dialysis and / or transplantation before the age of 5 years.[fetalmedicine.org]
  • The prognosis for PUV improves when detected early.[stanfordchildrens.org]


  • The etiology is unclear and the pathogenesis a subject of continuing debate. Clinical and pathologic experience with seven cases of prune-belly syndrome is reviewed.[ncbi.nlm.nih.gov]
  • They are organised into groups, and further divided into clinical, etiological or histopathological sub-types.[orpha.net]

  • In young and middle-aged women, gynecologic surgery, pregnancy, and cancers of pelvic organs are important etiologies of obstruction.[emedicine.medscape.com]
  • When deciding the most appropriate form of treatment, it's important to take into account the stricture etiology, location, and severity, prior treatments, comorbidities, and patient preference.[medicinenet.com]

  • Epidemiology Age Urinary tract obstruction occurs most commonly in the young and the old: In older men, this is a relatively common condition due to prostatic enlargement: Incidence of lower urinary tract symptoms (LUTs)/BPH averages 15 per 1,000 man-years[patient.info]
  • Most epidemiologic studies of obstruction are in selected populations or autopsy studies. In large surveys of elderly men for symptoms of urinary obstruction, a prevalence of 20-35% has been estimated.[emedicine.medscape.com]
Sex distribution
Age distribution


  • The pathophysiology, diagnosis and treatment of this iatrogenic type of female urethral obstruction are discussed.[ncbi.nlm.nih.gov]
  • Pathophysiology Normal urine production in an adult is about 1.5-2 L/day.[emedicine.medscape.com]


  • It will not prevent the abdominal wall deformity of the prune belly syndrome. The evidence suggests that to allow maximum time for lung development and to prevent increasing renal dysplasia, drainage should be performed before 18 weeks of gestation.[ncbi.nlm.nih.gov]
