Intermittent hydronephrosis is challenging to diagnose, often leading to delayed treatment. Early recognition of this condition in children with recurrent abdominal pain is crucial to prevent kidney loss.
Area of Science:
- Pediatric Urology
- Diagnostic Challenges in Nephrology
Background:
- Intermittent pelviureteric junction obstruction causes hydronephrosis, which is difficult to diagnose due to non-dilated collecting systems between pain episodes.
- Prompt investigation during painful crises is challenging, leading to initial misdiagnosis in many pediatric cases.
Observation:
- A study reviewed medical records of children operated for hydronephrosis between 2008-2012.
- 10 out of 76 children operated for pelviureteric junction obstruction met criteria for intermittent hydronephrosis.
Findings:
- The average diagnostic delay for intermittent hydronephrosis was 2 years and 4 months.
- Pyeloplasty was performed in 7 patients, while 3 patients required nephrectomy due to the condition.
Implications:
- Intermittent hydronephrosis constitutes a significant proportion of surgically treated hydronephrosis cases.
- Delayed diagnosis resulted in kidney loss in one-third of affected children, highlighting the need for increased clinician awareness.
- Recurrent, unexplained abdominal pain in children should prompt suspicion of urological issues, even with normal initial ultrasounds.

Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
