Papillary edema may be seen with "fuzzy" or feathery calyceal
Refinements in laparoscopic techniques have allowed renal pelvic, proximal ureteral and even calyceal
diverticular stones to be removed during a single operative setting.
The results of our study showed that several anatomical landmarks and angles provide an anatomical basis for safe and efficient renal access for lower calyceal
The kidney was systematically inspected, and lower calyceal
stones were removed with a basket or fragmented using Holmium:YAG laser lithotripsy.
5) Although these findings may be "typical" of GU TB, the differential diagnoses include partial staghorn stone, calyceal
diverticulum with stones, chronic pyelonephritis, cystic renal cell carcinoma with calcification, fungal infections and urothelial carcinoma.
9) The suggested mechanism for the urine extravasation includes rupture of the calyceal
fornix secondary to rapidly increasing intrapelvic pressures, with extravasated urine being re-absorbed by either the venous or lymphatic routes.
Extracorporeal shockwave lithotripsy for lower calyceal
stones: can clearance be predicted?
Metabolic abnormalities associated with calyceal
This relatively new technique is particularly beneficial for patients who are unsuitable for extracorporeal shock wave lithotripsy (ESWL) or percutaneous nephrolithotripsy (PCNL), patients with repetitive ESWL failure, obesity, hemorrhagic disease, lower calyceal
calculi, or calyceal
diverticular calculi, and patients who require multiple ESWL.
6) Aron and colleagues reported similar complication rates for superior and inferior calyceal
punctures in complex inferior calyceal
One must be cognizant of the adjacent anatomy and ensure calyceal
puncture and tract dilatation are not too far medial, which poses a risk for lumbar plexopathy as discussed in this case.
However, the current data suggest that a male infant with painless intermittent macroscopic hematuria, with radiological features of a non-invasive calcified renal mass within the upper pole calyceal
system, very likely has an ORTI.
