Study summary

Flexible cystoscopy has diagnostic as well as therapeutic role in many patients presenting in urology clinic with lower urinary tract symptoms (frequency, nocturia etc) and hematuria (blood in urine).

Pain associated with cystoscopy varies from patient to patient, majority requires local anesthesia or lubricant solution only. During flexible cystoscopy, lubrication, use of topical anesthesia and duration of cystoscopy are recognized as important factors contributing in severity of pain of which use of intraurethral gel left to individual preference. Various studies are available reporting the pain perception with use of various intraurethral gels. Even the highest level of evidence is unable to resolve the query.

With this study the investigators hypothesize that pain perception (recorded in form of pain score) during flexible cystoscopy can be reduced with use of per operative diclofenac(Non Steroidal Anti Inflammatory Drug)suppository in comparison to plain gel alone.

With better control of pain the investigators aim to increase patient comfort and compliance which will increase the patient satisfaction rate and early return to work.

Study arms

  • No intervention
    Gel only

    This group will be given only intraurethral gel during flexible cystoscopy.

  • Experimental
    Diclofenac and Gel

    This group will also receive intraurethral gel during cystoscopy but additionally diclofenac suppository will be given per rectally one hour before procedure as preemptive analgesia.

    Drug: Diclofenac

Interventions

  • DrugDiclofenac

    Also known as: Non steroidal anti-inflammatory drug

What researchers measure

Primary outcomes

  1. difference in pain score between two groups

    Patient under goes the procedure and with in the operating room the outcome assessor(who will be blinded to randomization) will record the pain score.

    Time frame: five minutes after procedure

Secondary outcomes

  1. Need of additional analgesia after the procedure

    Patient will be assessed for pain during the stay in recovery that usually last for an hour. If there will be need of additional analgesia (if patient reports pain score of more than 7 on visual analogue scale)the type of analgesia, dose and frequency will be noticed.

    Time frame: with in an hour after procedure

Other outcomes

  1. adverse effect of diclofenac suppository

    Diclofenac is safe according to the available literature however minority of patients may have skin itching or difficulty in breathing. Post procedure patient will also be observed for any side effect of diclofenac suppository (if received preoperatively.

    Time frame: 1 hour
