Experience and Security of the Hand-Assisted Laparoscopic Nephrectomy of a Living Donor in a Public Health Center

Post-Laparoendoscopic Single-Site Donor Nephrectomy Ipsilateral Testicular Pain, Does Operative Technique Matter? A Single Center Experience and Review of Literature

Aim

To assess incidence and characteristics of post-laparoendoscopic single-site donor nephrectomy (LESS DN) testicular pain.

Materials and Methods

A prospective comparative study of all male donors post-left LESS DN (group A) vs. postopen nephrectomies (group B) was performed at our center. Patients' demographics, perioperative data, and postoperative consultation reports were reviewed. Testicular pain, swelling, numbness, urinary symptoms, and sexual dysfunction were evaluated. Patients with a history of scrotal pathology or surgical procedure were excluded. Pain and tenderness were scored on a standard 10-point scale.

Results

From September 2017 to December 2020, 85 and 35 male patients of groups A and B met the evaluation criteria. Ipsilateral testicular pain developed in 11 patients (15.3%) and 2 patients (9.5%) in groups A and B, respectively. In most instances, the pain was mild to moderate in severity, started after 6 ± 2.1 and 4 ± 1.1 days postoperatively in groups A and B, respectively. Six patients in group A were evaluated with transscrotal ultrasonography that showed no abnormalities. All patients in both groups responded well to medical treatment.

Conclusions

Post-LESS DN ipsilateral testicular pain is usually mild and self-limited. Preoperative patient education and discussion of the possibility of development of testicular pain and its management should be an integral component of laparoscopic donor nephrectomy informed consent.

One-stop preoperative assessment of renal vessels for living donors with 3.0 T non-contrast-enhanced magnetic resonance angiography: compared with computerized tomography angiography and surgical results

OBJECTIVE

The study was to investigate the feasibility and accuracy of assessment for living renal donors before transplantation by using 3.0 T non-contrast-enhanced magnetic resonance angiography (NCE-MRA).

METHODS

30 renal donors were investigated and underwent computed tomography angiography (CTA) and 3.0 T NCE-MRA before nephrectomy. Two radiologists independently assessed arterial and venous anatomy and potential kidney lesions. The image quality score, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), diameters and lengths of renal arteries and veins were compared between CTA and NCE-MRA. Imaging findings were compared with the surgical results served as reference standard. Agreement was assessed using κ test. The Wilcoxon test and paired sample t test were used for statistically significant differences.

RESULTS

The results of image quality score for renal arteries and veins were highly consistent between the two radiologists in NCE-MRA (p < 0.001). There was no significant difference in the scores of renal arterial and venous branches between NCE-MRA and CTA (p > 0.05). The SNR and CNR of renal vessels were higher than CTA (p < 0.001). There were no statistically significant differences in the length of renal vessels measured by the two methods (p > 0.05), and the diameter was smaller than that of CTA (p < 0.05). The detection of normal renal arteries and early branches by both examination techniques was consistent with intraoperative findings. Both methods showed good consistency between the anatomical variation of renal vein and the intraoperative diagnosis (p < 0.001).

CONCLUSION

3.0 T NCE-MRA can be used for evaluation of main renal arteries and veins with high accuracy for anatomy and variation classification, and can be used for pre-operative vascular evaluation of living donor kidney transplantation.

ADVANCES IN KNOWLEDGE

3.0 T NCE-MRA can be used for evaluation of main renal arteries and veins with high accuracy for anatomy and variation classification, and can be used for pre-operative vascular evaluation of living donor kidney transplantation.

Persistent orchialgia after laparoscopic living-donor nephrectomy: an underestimated complication requiring information adjustment

PURPOSE

Laparoscopic living-donor nephrectomy (LLDN) is the gold-standard procedure for kidney procurement. Ipsilateral orchialgia has barely been described. Some authors reported that ligation of gonadal vein (GV) above iliac vessel bifurcation could prevent orchialgia. We aimed to assess incidence and duration of orchialgia after LLDN in male donors despite distal ligation of GV.

METHODS

Patients who underwent LLDN from 2014 to 2017 were included. Standard procedure consisted in distal ligation of GV, close to the renal vein confluence and proximal ureteral ligation. Patients' demographics, per-operative data, and post-operative consultation reports were retrospectively reviewed. Orchialgia and scrotal symptoms were assessed through a non-validated questionnaire by phone interview.

RESULTS

Sixty-nine donors were included. Orchialgia incidence and testicular swelling were 31.9% (n = 22) and 15.9% (n = 11), respectively. Median symptom duration was 15.5 months. Orchialgia led to medical consultation in 41.7% (n = 10) of cases. All patients declared having been informed, prior to donation, about possible residual pain but not specifically orchialgia.

CONCLUSION

Orchialgia after LLDN affects more than 30% of donors, despite distal ligation of GV and led less than 50% of them to medical consultation, suggesting a large underestimation in clinical practice. Emphasis should be put on this complication during pre-donation information.
