445 cases with upper urinary tract calculi, which were removed by various routes, were studied as to sizes (lengths and widths) of their stones and also as to weights for 304 cases in this series. The mean ± S.D. of lengths and widths, and mean weights, of calculi were as follows: 0.6±0.3cm and 0.4±0.2cm in 149 cases, and 0.1gm in 95 cases, for spontaneously discharged calculi (Table 1-3); 0.6±0.2cm and 0.4±0.1cm in 13 cases, and 0.1gm in 11 cases, for calculi by basket catheter extraction (Table 4-6); 1.1±0.5cm and 0.7±0.3cm in 189 cases, and 0.3gm in 145 cases, with ureterolithotomies (Table 7-9); 1.7±0.9cm and 1.3±0.7cm in 51 cases, and 1.3gm in 31 cases, with pyelolithotomies (Table 10-12); 2.8±1.6cm and 1.8±1.0cm in 43 cases, and 5.7gm in 22 cases, with nephrolithotomies, partial nephrectomies and nephrectomies (Table 13-20). It is suggested that the calculi smaller than 1.2cm in length and 0.7cm in width are possible to be discharged spontaneously, and the calculi smaller than 2.1cm in length and 1.2cm in width are to be expelled into the ureter from the renal pelvis.
