“…Lymphatic crossover channels are common in patients with filarial chyluria because of lymphangitis or obstructive lymphangiopathy. The direction of flow in the lymphatic channels, being a closed circulation system with a positive pressure, will converge to the point where the integrity of the channels has been breached [7–9]. Therefore, unilateral lymphography can detect LRF even when it is on the side opposite that where contrast agent is injected.…”

Objective To evaluate the usefulness of unilateral pedal lymphography in patients with ®larial chyluria. Patients and methods Of 114 patients with ®larial chyluria, all underwent lymphography (unilateral pedal in 106) and 55 underwent selective ureteric sampling for chyle. Results Unilateral pedal lymphography in the 106 patients detected lymphaticorenal ®stulae (LRF) in 104 (98%). Lymphatic crossover was seen in all 106 patients, from the second sacral segment to the ®rst lumbar segment. The most frequent crossover site was at the L5 level (87%). There was complete correlation between the side of LRF and the side of chyluria as assessed by selective ureteric sampling. Conclusion Unilateral pedal lymphography can detect LRF via lymphatic crossover even when it is on the opposite side from that injected with contrast agent. The advantages of unilateral lymphography over bilateral procedures are that it is easy to identify crossover channels, and the discomfort for the patient is reduced because there are fewer incisions and it is quicker. Unilateral lymphography is recommended as the initial method when lymphography is indicated in ®larial chyluria.

“…[1] In Western countries, however, chyluria is typically non-parasitic in nature, rare, and occurs most commonly secondary to retroperitoneal tumors and abscesses. [2] Postsurgical cases of chyluria have been reported as sequelae of urological procedures such as partial nephrectomy as well as radiofrequency (RF) ablation for renal tumors. [3,4] ese cases are rare and are thought to occur due to the formation of a fistulous connection between the lymphatics and the collecting system of the kidney.…”

Chyluria is a rare complication following renal intervention including partial nephrectomy and percutaneous ablation. To date, there are no reported cases of chyluria following renal cryoablation. An 82-year-old female patient at our institution underwent CT-guided percutaneous cryoablation for a renal cell carcinoma and presented with macroscopic fat in the urine 5 months after cryoablation. Presenting symptoms were polyuria, dysuria, and cloudy white urine. CT showed a fat-urine level in the ureter and bladder most consistent with chyluria. The patient experienced several episodes of presumptive lower urinary tract infection following diagnosis for which she was treated medically. Follow-up CT imaging 5 months post-diagnosis revealed persistent fat-fluid level in the collecting system and bladder. Operators performing renal cryoablation should be aware of the clinical and imaging manifestations of this complication.
