Long-Term Passive Ureteral Dilatation with Double-J Stent: Possibly an Effective Treatment for Recurrent Renal Colic Caused by Papillary Renal Necrosis
Bibliographic record
Abstract
Background: An uncommon cause of recurrent renal colic is mucous tissue passage secondary to renal papillae necrosis. Because of its low prevalence, the correct management of recurrent obstructive uropathy produced by renal papillary necrosis (RPN) is not well defined. Case Presentation: We present a case of recurrent renal colic associated with the expulsion of mucous tissue in a young woman's urine with a history of excessive consumption of nonsteroidal anti-inflammatory drugs (NSAIDs). The patient required multiple admissions to the emergency department because of recurrent episodes of renal colic. A retrograde pyelogram and histopathologic study of the expulsed tissue supported the diagnosis of RPN. The patient was managed with Double-J stents for 12 months, complete withdrawal of NSAIDs, and large volume intake of water. A satisfactory outcome was seen radiologically and endoscopically after treatment. The patient stopped experiencing new renal colic episodes because of the passive ureteral dilatation despite still presenting the mucous tissue expulsion in the urine. Conclusions: Passive ureteral dilatation with Double-J stents could possibly be an effective treatment for patients with recurrent renal colic secondary to persistent renal papillae necrosis.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
