“…8,10,45 Outside of the field of transplantation, it has been shown that right kidneys are overall more likely to have multiple renal veins. 60 This could contribute to the increased anastomosis time and the increase in technical complications. Unfortunately, no studies performed multivariate analyses which adjusted for this potential confounder.…”

Introduction: Transplantation of right kidneys can pose technical challenges due to the short right renal vein. Whether this results in inferior outcomes remains controversial.Method: Healthcare Database Advanced Search (HDAS) was used to identify relevant studies. Two authors independently reviewed each study. Statistical analyses were performed using random effects models and results expressed as HR or relative risk (RR) with 95% confidence intervals. Subgroup analyses were performed in kidneys from deceased donors (DD) and living donors (LD).Results: A total of 35 studies (257,429 participants) were identified. Both deceased and living donor right kidneys were at increased risk of delayed graft function (DGF; RR = 1.12[1.06-1.18] and RR = 1.33[1.21-1.46] respectively; both p < .0001). In absolute terms, for each 100 kidney pairs of DD kidneys transplanted there are 2.72 (1.67-3.78, p < .00001) excess episodes of DGF in right kidneys. Graft thromboses and graft loss due to technical failure was also significantly more likely in right kidneys, in both DD and LD settings. There was no evidence that laterality alters long term graft survival in LD or DD. Conclusion:Right kidneys have inferior early outcomes, with higher rates of DGF, technical failure and graft thrombosis. However, these differences are small in absolute terms, and long-term graft survival is equivalent.

“…The prevalence of multiple renal veins has been investigated in anatomical studies and by CT angiography [ 1–5 ]. In a meta-analysis of 105 studies, the mean incidence of multiple renal veins was 16.7% [ 1 ]. Multiple renal veins were much more common on the right (16.5%) than on the left side (2.1%).…”

As there is usually considerable overlap in the renal venous drainage, it is often possible to ligate supernumerary transplant renal veins in order to simplify the implantation procedure. Nonetheless, decisions about whether to implant multiple veins can be difficult and are usually made subjectively. Here, we describe the use of intraoperative Doppler ultrasound as an adjunct to decision-making when there are two renal veins and a novel technique for the sequential anastomosis of dual veins. The kidney was reperfused after anastomosis of the main renal vein with the second vein clamped. On-table Doppler ultrasound demonstrated reversed flow in diastole indicating that the second renal vein also needed to be anastomosed. By clamping the external iliac vein inferior to the first venous anastomosis it was possible to complete the lower polar renal vein anastomosis to the external iliac vein without interrupting the perfusion of the kidney.

Venous disorders are not limited to the extremities. Diseases of the leg veins, such as varicose veins and phlebothrombosis, can also affect the veins of the pelvic organs and the retroperitoneum. At the same time, pelvic and abdominal symptoms can sometimes have a phlebogenic cause. Chronic pelvic congestion syndrome has become widely recognised as a counterpart to chronic venous insufficiency of the leg veins, however the term does not adequately capture the complexity of the disorder, neither anatomically nor functionally.Clinical diagnoses and imaging, especially Duplex sonography of the retroperitoneal veins, prove to be considerably more difficult than in leg veins. In addition, there is a wide variation in the vessels. A profound knowledge of the anatomy of the pelvic and retroperitoneal vessels is needed to accurately interpret the findings. Knowledge of the major stages of embryonic development facilitates one’s understanding of the pathophysiological mechanisms.
