Where is the renal papilla?

12 year old DSH F/S.

Presented for recurrent FIC. Cat not currently having an “episode” but owners wanted urogenital ultrasound.

Bloodwork WNLs (BUN and CREA normal, CREA 160).

Bladder – WNLs except small amount of mildly echogenic material in gravity-dependent area of bladder –> cysto UA – TNTC RBCs, 0-3 WBC/hpf.

Right kidney – WNLs, measured 3.95cm. Renal pelvis 1mm.

Left kidney – small (2.95cm), irregular contour. Feeling really dumb here, but having difficulty pinpointing exactly where the renal pelvis is – can you please enlighten me? Was thinking this was a case of CKD LK but having troubles with exactly what the RP measurement would be….

Thanks

Sorry – I meant I am having troubles pinpointing the renal papilla (and as a result don’t know what to put for renal pelvis measurement).

Thanks

You can only really measure

You can only really measure the renal pelvis when dilated and its not dilated in these images. Here is an example of a pyelonephritis for example when you measure the renal pelvis.

Thanks for the reply. I can

Thanks for the reply. I can usually pick it out easily but found it wasn’t well defined with this kidney. Must be the CKD.
