As many expanding renal cysts distort the intrarenal caliceal
system, the urinary stasis and urinary crystals facilitated the formation and aggregation of renal calculus.
Totally ultrasonography guided PCNL (both in caliceal
puncture and tract dilation) is a good alternative to the fluoroscopic method and has satisfactory outcomes compared with the standard technique of PCNL without any major complications and with the advantages of preventing radiation hazards, preventing damage to adjacent organs, and checking for residual calculi.

calculi and staghorn stones in children less than 5 years of age.
We included patients with upper caliceal
, middle caliceal
and renal pelvic stones with stone burden [greater than or equal to] 2 cm, lower caliceal
stones [greater than or equal to] 1.5 cm, upper ureteral stones [greater than or equal to] 1 cm, extracorporeal shock wave lithotripsy-resistant stones [greater than or equal to] 1 cm, multiple location stones with stone burden [greater than or equal to] 2 cm, and staghorn stones.
The aim of our study was to evaluate the efficacy of postoperative prilocaine 2% injection into the skin, underskin, muscle and fascia layers in the acute pain management after a lower caliceal
puncture during PCNL.

Patients who had an upper caliceal
access procedure underwent a chest film to detect any chest complications.
The sonographic appearance of milk of calcium in renal caliceal
locations of stones is more predictive for stone-free rates for staghorn stones.
PCNL is associated with several concerns regarding the management of stone disease in malformed kidneys, including abnormal position with abnormal renal and caliceal
orientation, abnormal relations of calices to the renal pelvis and upper ureter, aberrant vasculature, relative kidney immobility impeding the maneuverability of rigid instruments, and abnormal relations with other organs, particularly the bowel.
