Laparoscopic ligation of the left spermatic vein did not significantly alter renal vein diameter or blood flow post-surgery. This procedure showed no impact on renal hypertension indicators in patients with varicocele.

Area of Science:

  • Urology
  • Nephrology
  • Vascular Surgery

Background:

  • Varicocele, an enlargement of veins within the scrotum, can lead to venous congestion.
  • Left-sided renal hypertension is a potential complication associated with varicocele due to venous overload.

Purpose of the Study:

  • To evaluate the impact of laparoscopic ligation of the left spermatic vein on renal function and venous anatomy.
  • To assess changes in renal arteries, renal veins, and inferior vena cava post-surgery.

Main Methods:

  • Color Doppler ultrasonography for assessing renal vessels.
  • Complex radionuclide study with 99mTc-pentatech for renal function evaluation.
  • Pre- and 12-month postoperative assessments in healthy individuals and varicocele patients.

Main Results:

  • No significant changes were observed in renal artery or inferior vena cava diameters.
  • No significant differences were found in renal vein diameters or blood flow velocities post-surgery.
  • Preoperative findings indicated left-sided renal hypertension in varicocele patients, attributed to left renal vein overload and compression.

Conclusions:

  • Laparoscopic ligation of the left spermatic vein did not significantly alter renal vein hemodynamics or renal function 12 months post-procedure.
  • The study suggests that while varicocele may cause preoperative renal venous congestion, the surgical intervention does not lead to significant postoperative changes in these parameters.
