Now a days for a few kidney patient on inevitable condition they remove one of the kidneys. Human body by nature right artery fed the blood to the right kidney and left artery to the left kidney. After removing how is this done?
If one of the two kidneys ( for example, the right one) is removed, the right renal artery will be ligated as well as the renal vein and the urether leading the urine from this kidney to the bladder. This is named nephrectomi.
By the way, one can live with only one functioning/existing kidney.
If one kidney is lost, either by accident or by kidney donation, the remaining kidney is going to grow in its functional capacity, it is called hypertrophy, which is the higher, the younger the human being is, it may reach up to 150% of the remaining kidney function.
All good points mentioned so far. I’m not sure I completely understand the question. I think there are perhaps two questions at hand: one about kidney blood flow and one about impacts of living with one kidney.
Kidney transplantation and Living kidney donation provide a nice model to describe both. In living kidney donation, an open or laparoscopic nephrectomy is performed. The renal arteries/veins are ligated in the donor and they are left with one kidney.
The recipient of a kidney transplant ends up with a surgically created anastomosis of the donor renal arteries and veins to the iliac system. This is typically performed on the right side but can be on the left. Either way you could have a donated left kidney with left renal arteries and veins connected to the recipients iliac system on the right. Point being laterally doesn’t really matter: it’s more about the patency of the vessels and surgical technique.
These are generalities/always exceptions to the rules/I’m not a transplant surgeon.
To summarize- laterality is less important in kidney blood flow compared to vessel/anastomosis characteristics.
In terms of living with one kidney, it depends. Like others have mentioned, if congenitally absent or atrophies early in life, more likely that glomerular hypertrophy and secondary FSGS develop.
For people who are living donors, typically their remaining kidney compensates without developing secondary FSGS and their kidney function can end up being around 75% of their pre-donation GFR.
In conclusion- 1) Kidney blood flow is typically fine after nephrectomy and as transplant shows laterality of vessels is less important. 2) How someone does with one kidney is complicated and depends on timing/circumstances, but in the best of cases (living donation), people live relatively normal lives with kidney function that can be 75% of their pre-donation kidney function.
