About this study

This study was planned as a randomized controlled trial to investigate the effects of Kegel pelvic floor muscle exercises on urinary retention and comfort levels of patients after lumbar disc herniation surgery.

Read the detailed description

Postoperative urinary retention is the inability to urinate despite having a full bladder after surgery. It is a relatively common complication of both outpatient and inpatient procedures. Most cases are transient and are managed by temporarily emptying the bladder with bladder catheterization.

Studies in the literature report that transient postoperative urinary retention is common after cervical and lumbar spine surgery procedures. This situation is of great importance in terms of healthcare services, as it can increase both the length of hospital stay and the cost.

Kegel pelvic floor muscle exercises involve the repeated contraction and relaxation of the muscles that form part of the pelvic floor. With these exercises, pelvic floor blood circulation can be increased, pelvic floor muscle tension can be increased, and the contraction of the relaxed bladder can be stimulated indirectly by repeated contraction and relaxation of the pelvic floor muscles, and urine output can be achieved. Therefore, we think that these exercises, which are safe, cost-effective exercises that can be easily applied by healthcare personnel, and patient comfort among nursing practices to improve perioperative results and functional status, will have an effect in preventing urinary retention.

There are no experimental studies in the literature evaluating the effect of Kegel exercises applied after lumbar disc herniation surgery on urinary retention. Therefore, this study was planned to be conducted in patients who will undergo lumbar disc herniation surgery.

This study was planned as a single-center prospective randomized controlled experimental study. After obtaining verbal and written consent from the patients before surgery, the study will be conducted with various data collection forms.

These forms; Patient Information Form, Postoperative Data Collection Form, Numeric Rating Scale (NRS) to determine the pain level of the patients and Visual Analog Scale (VAS) to evaluate the comfort level. Patients will be randomized. Group I will be the Kegel pelvic floor muscle exercise group (n=29), Group II will be the control group (n=29). It is planned to measure the urinary retention and comfort levels of both groups in the postoperative period.

    After the surgery, the patients will be taken to the clinic room in a supine position and the researcher will perform the Kegel pelvic floor muscle exercises three times at the 1st, 4th and 7th hours within the first 8 hours after the patients are taken to the clinic room.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effect of Kegel pelvic floor muscle exercises on urinary retention of patients after lumbar disc herniation surgery.

    Kegel pelvic floor muscle exercises will affect the urinary retention of patients after lumbar disc herniation surgery. Urinary retention will be evaluated using the Postoperative Data Collection Form developed by the researchers based on the literature. This form includes items assessing signs and symptoms of urinary retention within the first 8 hours postoperatively, such as pressure in the lower abdomen, pain in the lower abdomen, feeling of restlessness, and desire to urinate within 8 hours. Each symptom is assessed separately using the Visual Analog Scale (VAS).

    Measured: After completing Kegel pelvic floor muscle exercises in the first 8 hours after surgery.

Secondary outcomes (1)

  1. Effect of Kegel pelvic floor muscle exercises on comfort level after lumbar disc herniation surgery

    Kegel pelvic floor muscle exercises will affect comfort level of patients after lumbar disc herniation surgery. The comfort level of the patients will be evaluated with VAS. VAS is used to convert some unmeasurable values into numerical values. VAS is a horizontal line with a length of 10 cm. According to VAS, 0 is the lowest level and 10 is the highest level. Patients will be asked to mark these levels on the 10 cm line.

    Measured: After completing Kegel pelvic floor muscle exercises in the first 8 hours after surgery.
