Abdominal Distension
  • This was associated with abdominal distension, and leakage of urine from the abdominal wound. Contrast studies suggested that the silicone catheter had migrated into the rectum and the child was re-explored.[bjuinternational.com]

Burning Sensation
  • Both urethras were continent, and there was no complaint of a burning sensation or dribbling of urine during micturition. Physical examination revealed no other associated congenital abnormality. External genitalia were well developed.[ncbi.nlm.nih.gov]
Renal Insufficiency
  • Patients may also present as urinary tract obstruction or chronic renal insufficiency. Diagnosis is made during a physical examination, supplemented by voiding cystourethrography, retrograde urethrogram, and urethrocystoscopy.[ncbi.nlm.nih.gov]
  • Patients may also present as urinary tract obstruction or chronic renal insufficiency.[read.nxtbook.com]
  • Urologic sequelae of urethral valves include urinary hesitancy, decreased urinary stream, urinary tract infection, overflow incontinence, myogenic bladder malfunction, vesicoureteral reflux, upper urinary tract damage, and renal insufficiency.[merckmanuals.com]
Kidney Failure
  • Upper tract infections, by contrast, can be serious for both adults and children, causing high fevers, back pain, severe generalized discomfort, and even leading to kidney failure or septicemia (infection spreading throughout the body by way of the blood[healthofchildren.com]


  • Infection of your urethra is another cause - for example: Sexually transmitted infections such as gonorrhoea or chlamydia. Infection as a complication of long-term use of a tube (catheter) to drain your bladder.[patient.info]

  • Holst et al. have described fulguration of an atypical urethra as another treatment option 11. Our treatment technique in this case was unique (minimally invasive) and successful.[f1000research.com]
  • Treatment of urethral duplication should be individualized based on the anatomic variant and also clinical symptoms and severity of anomaly. Some patients do not require treatment if they are free from infection and incontinence.[ncbi.nlm.nih.gov]

  • The precise etiology of both the conditions remains elusive and various postulates exist. Due to the rarity of this association, one may not identify both the problems which may present as a diagnostic challenge.[bjuinternational.com]
