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]

• Fishing

  The researchers then transferred an intact human BNC2 copy into the manipulated fish embryos. This considerably decreased the number of urinary tract malformations in these fish. [uni-bonn.de]

• Receding Chin

  Other anomalies include cryptorchidism, pulmonary hypoplasia, club foot and features of Potter sequence including wide-set eyes, flattened nose, receding chin and large, low-set ears deficient in cartilage. [orpha.net]

• 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]

  Vesicoureteral reflux in the absence of urinary tract infection or bladder neck obstruction often resolves with age. [accessmedicine.mhmedical.com]

  In the bladder neck obstruction and BPH models, even greater velocity inlets were required for convergence, as expected. Interestingly, for the first-angle case, however, the flow converged at an inlet of 1.166 m/s. [jyi.org]

• 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]

• Anuria

  Complete obstruction causes complete anuria. Investigation Renal function will only be severely altered if obstruction affects both kidneys (or a single functioning kidney). Rectal/vaginal examination may reveal enlarged prostate or pelvic tumour. [edrep.org]

  Patients range from having oliguria/anuria to only having asymptomatic hydronephrosis that is incidentally identified through imaging or elevated creatinine levels. [amboss.com]

  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]

In addition, children with incontinence or urinary tract infection need a workup because they may also have some type of urinary tract obstruction. [emedicine.medscape.com]

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]

Prognosis Prognosis depends on the degree of dilation of the urinary tract and the degree of renal functional impairment. Outcome is typically good in cases with normal amniotic fluid volume. [orpha.net]

The prognosis is directly proportional to the renal function. [jamanetwork.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 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]

In cases of siblings with Prune Belly Syndrome and mosaicism, a genetic etiology has been suggested but the majority of cases are of a sporadic nature. Diagnostic methods Diagnosis is usually antenatal. [orpha.net]

In children, infection is less common an etiology. [emedicine.medscape.com]

This can be done by either catheterization or surgical intervention depending on the etiology of the obstruction 2. On imaging consider: neurogenic bladder posterior urethral valves [radiopaedia.org]

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]

The pathophysiology, diagnosis and treatment of this iatrogenic type of female urethral obstruction are discussed. [ncbi.nlm.nih.gov]

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]
