Prophylactic treatments with sodium bicarbonate or potassium citrate did not reduce post-urodynamic study dysuria compared to placebo. Most patients experienced some discomfort, with severe cases more common in males, unrelated to urinary tract infections.

Area of Science:

  • Urology
  • Pharmacology

Background:

  • Urodynamic studies are common diagnostic procedures.
  • Dysuria (painful urination) can be a bothersome side effect following these studies.
  • Prophylactic treatments are sometimes used to mitigate post-procedure discomfort.

Purpose of the Study:

  • To evaluate the efficacy of sodium bicarbonate and potassium citrate in preventing dysuria after urodynamic studies.
  • To compare these prophylactic agents against a glucose placebo.

Main Methods:

  • A randomized controlled trial involving 324 patients.
  • Participants received prophylactic sodium bicarbonate, potassium citrate, or a glucose placebo.
  • Urine infection screening and dysuria assessment via postal questionnaire were conducted pre- and post-procedure.

Main Results:

  • 63% of patients reported some degree of dysuria.
  • Severe and prolonged dysuria occurred in 6.3% of patients, predominantly males.
  • Neither sodium bicarbonate nor potassium citrate showed a significant benefit over placebo in preventing dysuria.

Conclusions:

  • Prophylactic administration of sodium bicarbonate or potassium citrate is ineffective in preventing dysuria post-urodynamic studies.
  • Severe, prolonged dysuria was not linked to urinary tract infections or specific urodynamic diagnoses.
  • Further investigation into the causes and management of post-urodynamic dysuria is warranted.
