Effects of Rectal Indomethacin Suppository on Postoperative CRBD in Patients Undergoing LRP

25 de maio de 2026 atualizado por: Diansan Su, Zhejiang University

Effects of Rectal Indomethacin Suppository on Postoperative Catheter-Related Bladder Discomfort in Patients Undergoing Laparoscopic Radical Prostatectomy: A Randomized Controlled Trial

The postoperative incidence of catheter-related bladder discomfort (CRBD) ranges from 47% to 95%. It increases postoperative pain and agitation, thus requiring early intervention. Although a variety of drugs are used for the prevention or treatment of CRBD, the adverse reactions of most of these drugs have limited their clinical application. In long-term clinical practice, we found that indomethacin suppository has a good therapeutic effect on the discomfort of pelvic-related organs caused by nociceptive stimulation. However, its preventive effect on CRBD has not been reported yet. We hypothesized that indomethacin suppository has a preventive effect on postoperative CRBD. To verify this hypothesis, patients undergoing laparoscopic radical prostatectomy were enrolled in the study. Patients in the intervention group received 50 mg of indomethacin suppository via the rectal route immediately after surgery, while those in the control group received no treatment. The severity of CRBD, pain scores, consumption of analgesics, other perioperative adverse reactions, and patient satisfaction were observed and recorded at 0, 1, 2, and 6 hours after surgery.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Sem intervenção: Control group
No indomethacin suppository will be administered transanally at the end of surgery.
Experimental: Rectal administration of indomethacin suppository
Rectal administration of indomethacin suppository immediately at the end of surgery
Outro: Indomethacin suppository
All patients received preoperative education on distinguishing catheter-related bladder discomfort (CRBD) from surgical somatic pain. Anesthesia was induced with sufentanil 3μg/kg, propofol 2mg/kg and rocuronium 0.6mg/kg. Anesthesia was maintained with combined propofol, remifentanil and sevoflurane. Fifteen minutes before surgery completion, intravenous ondansetron 4 mg was given for postoperative nausea and vomiting prophylaxis, and sufentanil 1 μg/kg was administered for postoperative analgesia. Drugs potentially interfering with study outcomes including dexmedetomidine, dezocine, tramadol and other non-steroidal anti-inflammatory drugs were prohibited. At the end of surgery when removing sterile drapes, interventions were performed as follows: Rectal administration of 50 mg indomethacin suppository.

Medidas de resultados primários

Medida de resultado
Descrição da medida
Prazo
The incidence of moderate to severe CRBD within 0-1 hour after surgery
Prazo: The postoperative time was calculated from the moment the patient was extubated, and the patient's catheter-related bladder discomfort (CRBD) was assessed immediately after extubation. Patients will be followed during the first hour postoperatively.

Catheter-related bladder discomfort will be assessed immediately after extubation.

The severity of catheter-related bladder discomfort was graded as follows:

0 score: no discomfort;

  1. score (mild): discomfort reported only on questioning;
  2. score (moderate): discomfort reported spontaneously without behavioral response;
  3. score (severe): discomfort reported spontaneously with behavioral responses (e.g., flailing limbs, vocalization, or attempting to remove the catheter).

The incidence of moderate and severe CRBD within 0-1 hour postoperatively will be recorded.
The postoperative time was calculated from the moment the patient was extubated, and the patient's catheter-related bladder discomfort (CRBD) was assessed immediately after extubation. Patients will be followed during the first hour postoperatively.
