Table 5 Univariate analysis of operative factors during PCNL predicting the need for angioembolization
From: Utility of POPVESL scoring system in the management of renal pseudoaneurysm: a retrospective study
S. No | Factor | Conservative (n = 4) | Angioembolization (n = 36) | p Value |
|---|---|---|---|---|
1) | Access to renal stone through different calyx | |||
a) | Inferior calyx (12 cases) | 1 (25%) | 11 (30%) | 1.00 |
b) | Middle calyx (2 cases) | 1(25%) | 1 (2.7%) | 0.1923 |
c) | Superior calyx (10 cases) | 0 (0%) | 10 (27.7%) | 0.5558 |
d) | Multiple calyx (16 cases) | 2 (50%) | 14 (38.8%) | 1.00 |
2) | Stone location | |||
a) | Solitary stone location (21 cases) (Pelvic stone, stone in one calyx) | 2 (1,1) | 19 (11,8) | 1.000 |
b) | More locations (19 cases) (Staghorn calculus involving renal pelvis and multiple calyces, stone in ≥ 2 calyces) | 2 (1,1) | 17 (10,7) | |
3) | Duration of surgery (mean ± S.D.) (minutes) | 52.5 ± 6.4 | 59 ± 16 | 0.396 |
4) | Stone burden (in mm) (median ± S.D) | 24.72 ± 5.7 | 36.00 ± 9.9 | 0.123 |
