Laparoscopic partial nephrectomy (LPN) offers faster recovery than open partial nephrectomy (OPN), with earlier diet resumption and discharge. However, OPN remains preferred for larger or obligatory partial nephrectomies due to tumor characteristics.

Area of Science:

  • Urology
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Laparoscopic partial nephrectomy (LPN) is increasingly used for renal tumors.
  • Partial nephrectomy is technically challenging laparoscopically compared to open partial nephrectomy (OPN).

Purpose of the Study:

  • To compare outcomes of LPN and OPN for renal tumors.
  • To evaluate tumor characteristics and early outcomes between LPN and OPN groups.

Main Methods:

  • Retrospective analysis of 66 LPN and 59 OPN cases (2000-2004).
  • Comparison of operative time, blood loss, renal function (creatinine), diet resumption, length of stay, tumor size, pathology, and complications.
  • Statistical analysis using Student's t-test (P < 0.05).

Main Results:

  • LPN had significantly shorter operative times (144 vs. 239 min) and less blood loss (236 vs. 363 mL).
  • LPN patients resumed diet earlier (24 vs. 41 h) and had shorter hospital stays (82 vs. 129 h).
  • OPN group had larger tumors (3.4 vs. 2.2 cm) and more malignant subtypes; some OPN cases were obligatory partial nephrectomies.

Conclusions:

  • LPN provides early functional benefits over OPN for small renal tumors.
  • OPN is still utilized for larger tumors or when partial nephrectomy is obligatory, with good outcomes.
  • Patient groups were not evenly matched for tumor size and pathology.
