Brief summary

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.

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.

Interventions

Under general anesthesia, patients who are planned to perform multiport laparoscopic surgery for resection of solid organs including kidney or bladder will undergo Transvaginal NOSE

Under general anesthesia, patients who are planned to perform multiport laparoscopic surgery for resection of solid organs including kidney or bladder will undergo transabdominal specimen extraction with incision elongation

Inclusion criteria

* Patients who are accessible with vaginal approach * 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

Design outcomes

Primary

MeasureTime frameDescription
Patient and Observer Scar Assessment Scale (POSAS)post-op 1 weekCosmetic 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?
