There is no vascularity within the structure. The structure does not look like a polyp or transitional carcinoma. Because the structure looked a bit like a part of a catheter, we asked the patient about a previous catheterization of the bladder. He deni

There is an increased vascularity in the bladder wall indicating a cystitis. Because the kidneys are always included in the ultrasound examination of the urinary tract we also examined the kidneys.

Longitudinal image of the left kidney. The lowerpole is not well defined. Can you think of an abnormality that can explain this fact and the position of the tumor anterior of the aorta? Of course a CT scan was performed.

CT scan of the lowerpole of the kidneys. There is a horseshoe kidney. The mass in the lowerpole of the right kidney is clearly seen and is located anterior of the aorta.

Conclusion

During cystoscopy a foreign body in the bladder was found. The patient admitted auto manipulation during which a silicone string was lost in the bladder. The foreign body could be removed endoscopically. The renal mass proved to be a renal cell carcinoma, that had been incidentally discovered. The normal treatment for a renal cell carcinoma is a nephrectomy. Because the patient in this case has a horseshoe kidney, a nephrectomy is not possible. The patient was referred to a specialized urological center for a partial nephrectomy.
