Laparoscopic Living Donor Nephrectomy: A Single Center Comparison of Three Different Techniques

Minimally Invasive Laparoscopic Donor Nephrectomy With a Pfannenstiel Incision Using Size-Reduced Trocars

BACKGROUND

Laparoendoscopic single-site surgery is performed during laparoscopic donor nephrectomy (LDN) to reduce donor invasiveness. However, the procedure is difficult and does not improve cosmesis when the incision is made at the umbilicus. Therefore, we proposed a minimally invasive LDN with a Pfannenstiel incision using size-reduced trocars (mLDN) to achieve cosmesis and operability and aimed to assess its efficacy and safety.

METHODS

A total of 27 patients who underwent mLDN were recruited. Data on estimated blood loss, operative time, pneumoperitoneum time, warm ischemic time (WIT), complication rate, non-steroidal anti-inflammatory drugs (NSAIDs) used, and recipient serum creatinine levels were collected retrospectively. In mLDN, the Pfannenstiel position was incised to approximately 6 cm to retrieve the kidney, and three size-reduced trocars were placed in the left upper abdomen (2.5 mm and 5 mm) and umbilicus (5 mm).

RESULTS

The median operation time and pneumoperitoneum time were 245 and 194 minutes, respectively. The median WIT was 276 seconds, and the serum creatinine levels of the recipients at seven days and one, three, six, and 12 months were significantly improved compared with baseline. No intra- and postoperative complications (Clavien-Dindo grade ≥ 2) were observed, and no patients used additional NSAIDs after the operation. The scarring in the mLDN group was unnoticeable postoperatively.

CONCLUSIONS

mLDN can be performed safely, with high cosmesis, and with operability similar to that of conventional LDN. Although the WIT tended to be long, the function of the harvested kidney was maintained, and the use of analgesic NSAIDs was lower in this procedure. Our procedure should be considered as an option for LDN.

A comparison of pre- and post-operative outcomes in living donors undergoing transperitoneal laparoscopic nephrectomy and open nephrectomy: a retrospective single-center study

BACKGROUND

Kidney transplantation is often regarded as the preferred therapy for end-stage renal disease. Several surgical procedures have been developed to reduce postoperative donor complications, while maintaining kidney quality.

OBJECTIVE

This study aimed to compare the preoperative and postoperative outcomes of living kidney donors who underwent either transperitoneal laparoscopic nephrectomy or open nephrectomy.

DESIGN AND SETTING

Retrospective study conducted in Istanbul, Turkey.

METHODS

Fifty-five living-related kidney donors underwent nephrectomy and were retrospectively divided into two groups: 21 donors who underwent open nephrectomy (Group 1) and 34 donors who underwent transperitoneal laparoscopic nephrectomy (Group 2).

RESULTS

In comparison to the donors who underwent open nephrectomy, those who underwent transperitoneal laparoscopic nephrectomy had significantly shorter postoperative hospital stays (2.3 ± 0.2 versus 3.8 ± 0.8 days, P = 0.003), duration of urinary catheterization (1.2 ± 0.8 days versus 2.0 ± 0.7 days, P = 0.0001), operating times (210 ± 27 minutes versus 185 ± 24 minutes, P = 0.02), and less blood loss (86 ml versus 142 ml, P = 0.048). There was no statistically significant difference between the two groups with regard to the estimated blood transfusion and warm ischemia time. The preoperative week, first postoperative week, and 1-month postoperative serum creatinine levels were comparable between the groups.

CONCLUSIONS

Laparoscopic donor nephrectomy can be safely performed at centers with expertise in laparoscopic surgery. Laparoscopic donor nephrectomy has better outcomes than open donor nephrectomy in terms of length of hospital stay, duration of urinary catheterization, operating time, and blood loss.
