During PCNL, air may enter renal veins from the pelvicalyceal
12,13) Although rare, tumor herniation into the pelvicalyceal
system and renal sinus is characteristic and may result in hydronephrosis and hemorrhage.
The gross specimen showed a shrunken kidney and a distended pelvicalyceal
system containing a calculus with thick pus.
Neoplasms of the upper urinary tract: a review with focus on urothelial carcinoma of the pelvicalyceal
system and aspects related to its diagnosis and reporting.
The sections from various representative areas revealed dilated pelvicalyceal
system lined by metaplastic squamous epithelium and shows changes of chronic pyelonephritis (Fig 2).
0 cm, and it was well-confined within the renal and pelvicalyceal
Percutaneous nephrolithotomy in renal anomalies of fusion, ectopia, rotation, hypoplasia, and pelvicalyceal
aberration: Uniformity in heterogeneity.
Air was noted in the pelvicalyceal
system and the renal parenchyma (Figure 1).
The bladder, renal pelvicalyceal
system, ureters, and the proximal urethra are lined by urothelial mucosa, formerly called transitional mucosa.
Typically, the pelvicalyceal
system is involved first, spreading from the medullary region to the cortex.
Intravenous pyelography, performed to rule out focal pelvicalyceal
dilatation, revealed a focal space-occupying lesion with a mild displacement of upper pole calyces.
The following inclusion criteria were applied: patients with renal stones that were removed without significant (more than 4 mm) residual fragments, no perforation in the pelvicalyceal
system during PCNL and patients with single access.
