Summary
Needlescopic (2 mm) instruments offer a promising approach for minimally invasive urologic surgery. This technique is safe and feasible in select patients, potentially reducing recovery time and improving cosmetic outcomes.
Area of Science:
- Minimally Invasive Surgery
- Urologic Surgery
- Surgical Technology
Background:
- Minimally invasive surgery is advancing with smaller instrumentation.
- Needlescopic surgery utilizes 2-mm instruments and optics.
- Current literature lacks extensive data on needlescopic urologic procedures.
Purpose of the Study:
- To evaluate the initial experience with needlescopic instruments in therapeutic minimally invasive urologic procedures.
- To assess the feasibility, safety, and outcomes of needlescopic urologic surgery.
Main Methods:
- Needlescopic techniques were applied to various urologic surgeries.
- Procedures included adrenalectomy, nephrectomy, cyst marsupialization, orchiopexy, lymphocele marsupialization, and pelvic lymph node dissection.
Main Results:
- 42 needlescopic procedures were performed in 39 patients.
- The needlescopic success rate was 90.5%, with 3 conversions to conventional laparoscopy and 1 to open surgery.
- Average surgical time was 132 minutes, with an average blood loss of 67 mL. 33.3% of procedures were outpatient, and 94.9% of patients discharged within 23 hours. The overall complication and conversion rate was 14.3% with no mortality.
Conclusions:
- Needlescopic urologic surgery is feasible and safe in select patients.
- This approach may lead to reduced postoperative pain, shorter hospital stays, and faster recovery.
- Further development of 2-mm instrumentation and optical technology is warranted.
