Transvaginal Versus Transabdominal Extraction of Laparoscopically-excised Kidney Specimen

November 22, 2021 updated by: Seoul National University Bundang Hospital

A Prospective Randomized Controlled Study of Transvaginal Versus Transabdominal Extraction of Laparoscopically-excised Kidney Specimen (STTELS)

The aim of this study is to evaluate the outcomes of transvaginal natural orifice specimen extraction (NOSE) in patients who are planning multiport laparoscopic surgery for resection of kidney.

Study Overview

Detailed Description

Study design:

This is a prospective, randomized, single center trial. This clinical trial was approved by the Institutional Review Boards.

Study process:

All patients gave informed written consent after being informed of the details of the study. Subjects were randomized into either the experimental group (specimen removal through posterior vagina fornix incision) or control groups (specimen removal through extended abdominal incision). All participants underwent demographic and history taking, laboratory tests, a gynecologic examination to determine whether specimen removal through vagina is possible.

To evaluate cosmesis, patient satisfaction and quality of life VAS (Visual Analogue Scale), SF-12 (Short Form-12) health survey, BIQ (Body Image Questionnaire) and POSAS (the Patient and Observer Scar Assessment Scale) will be sent to the patients 6 months after the surgery.

Description

Inclusion Criteria:

  • Patients scheduled for laparoscopic resection of kidney for benign or malignant diseases
  • Patients with normal cervical cancer screening tests within the last 3 years except inflammatory findings

Exclusion Criteria:

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient and Observer Scar Assessment Scale (POSAS)
Time Frame: post-op 1 week

Cosmetic outcomes of scar assessed by Patient and Observer Scar Assessment Scale (POSAS) 1 week and 8 weeks after surgery. The POSAS is the international validated scar assessment questionnaire that measures quality of the scar from the perspective of both patient and observer.

observer scar assessment scale (OSAS): good (1) - bad (10)

- vascularization/ pigmentation/ thickness/ relief/ pliability

patient scar assessment scale (PSAS): No (1) - Yes (10)

  • Is the scar painful?
  • Is the scar itching?
  • Is the scar color different from the color of your normal skin?
  • Is the stiffness of the scar different from the color of your normal skin?
  • Is the thickness of the scar different from the color of your normal skin?
  • Is the scar more irregular than your normal skin?
post-op 1 week
