Page kidney or Page phenomena is a potentially reversible form of secondary arterial hypertension caused by external compression of the renal parenchyma by some perirenal process. [1] Any process that causes mass effect can be a potential cause of Page kidney.
the causes for this condition are the following: [citation needed] Obstruction by deep vein thrombosis or tumors (most commonly renal cell carcinoma); Compression through external pressure by neighbouring structures or tumors, either by significantly compressing the vein or by promoting thrombosis by causing turbulence by disturbing the blood flow.
Renal autotransplantation: transfer of a kidney from its original location into the body to another location to prevent venous compression. [6] LRV transposition is the most common procedure done followed by renal autotransplantation and LRV bypass. [6] In all cases for open procedures, data is limited for long term follow-up. With respect to ...
The increased intra-abdominal pressure leads to compression of the renal veins, which, in turn, to an oliguria that is unresponsive to fluid resuscitation. Diagnosis should be based on clinical findings in conjunction with a measurement of a bladder pressure. The trend of the bladder pressure may be more helpful than the absolute number. [12]
This relieves the obstruction, but leads to the loss of nephrons and renal function. With newer microscopic techniques, surgeons are now able to re-route the renal vasculature and relieve the compression on the affected calyces, while sparing the nephrons and renal function. This technique is known as Fraley's infundibulopyelostomy. [14]
immediate X-ray of just the renal area; 5 minute X-ray of just the renal area. 15 minute X-ray of just the renal area. At this point, compression may or may not be applied (this is contraindicated in cases of obstruction). In pyelography, compression involves pressing on the lower abdominal area, which results in distension of the upper urinary ...
In males and females, both internal and external urethral sphincters function to prevent the release of urine. The internal urethral sphincter controls involuntary urine flow from the bladder to the urethra, whereas the external urethral sphincter controls voluntary urine flow from the bladder to the urethra.

Any external compression (tourniquet, orthopedic casts or dressings applied on the affected limb) should be removed. Cutting of the cast will reduce the intracompartmental pressure by 65%, followed by 10 to 20% pressure reduction once padding is cut. After removal of the external compression the limb should be placed at the level of the heart.
