    The new pressure-controlled drainage system for transurethral resection of the prostate (TURP) is more efficient than suction drainage. It reduces irrigant volume and blood loss while increasing the resection rate for improved TURP outcomes.

    Area of Science:

    • Urology
    • Surgical Technology

    Background:

    • Transurethral resection of the prostate (TURP) is a common procedure for benign prostatic hyperplasia.
    • Continuous flow resectoscopes aim to improve surgical efficiency and safety.
    • Existing drainage systems present challenges in maintaining optimal surgical conditions.

    Purpose of the Study:

    • To compare the efficacy of a novel intrinsic bladder pressure-controlled drainage system with a conventional suction drainage system during TURP.
    • To evaluate key performance metrics including irrigant volume, blood loss, and resection rate.

    Main Methods:

    • A randomized controlled trial involving 31 patients undergoing TURP.
    • Patients were assigned to either the pressure-controlled drainage group (17 patients) or the suction drainage group (14 patients).

  • Surgical outcomes such as irrigant volume, blood loss, resection rate, irrigant absorption, and intravesical pressure were measured.

    • Main Results:

    • The pressure-controlled drainage system required significantly less irrigant volume and resulted in lower operative blood loss per gram of resected tissue.
    • A significantly greater resection rate (gram per minute) was observed with the pressure-controlled system.
    • Both systems demonstrated minimal irrigant absorption with no significant differences in weight gain, hematocrit, serum osmolality, or serum sodium.
    • No significant difference in intraoperative intravesical pressure was noted between the groups.
    • The suction drainage system experienced pump drainage failures, leading to reduced visibility and increased resection time.

    Conclusions:

    • The pressure-controlled continuous flow drainage system offers superior efficiency and ease of use compared to the suction drainage system for TURP.
    • This novel system provides constant, improved visibility and uninterrupted resection, enhancing the overall surgical experience and potentially patient outcomes.
