No significant differences in number of analgesic doses given in hospital and in mean pain

scores over the 48-hour time period were observed. Mean analgesic use at home was higher for

SO(p<0.01). Mean OpT was not significantly different with ITT approach. Per treatment(including

conversions) analysis showed that IO was 7 min faster(40±11vs.33±15; p<0.01). Conversions

occurred in 16/99(16 %) testes(75 %-canalicular). Overall complication rate=3 %(1-reascent/1-

incision dehiscence-SO; 1-wound infection-IO).

CONCLUSIONS

We found no difference in post-operative pain, analgesic consumption, OpT(ITT) and complications

between IO and SO. SO may not be a suitable approach for all patients with canalicular testes. Its

indications may need to be tailored to testis position for optimal results.

PURPOSE

The effort to decrease the frequency of unjustified laparoscopic interventions in cases of unilateral

non-palpable cryptorchidism determines the interest towards revealing the diagnostic criteria for

optimization of tactical surgery planning. Contralateral testicular volume can be employed as such

criterion.

MATERIAL AND METHODS

Сontralateral testicular volume was prospectively studied in 76 patients (up to 9 years old) with

unilateral nonpalpable forms of cryptorchidism. In all patients, the length, width, and height of the

contralateral testis were measured. Testicular volume=length*width*height*0.71. Depending upon

the undescended testicle condition, the patients were subdivided into two groups: those with vi-

able and nonviable testes. A comparison of basic data in the groups was carried out using the

Mann-Whitney test. To build the diagnostic model, logical regression was used. We analyzed the

significance of regression coefficients evaluating for the regressor the odds ratio (OR) and the 95 %

confidence interval. A Receiver Operating Characteristic (ROC) curve was built then for the model

and a threshold level was selected to match the optimal ratio between sensitivity and specificity.

RESULTS

Among the 78 patients, viable testes (intraabdominal or inguinal) were found in 41 (52.6 %), and in

37 (47.4 %) nonviable or missing testes were found. Whenever the contralateral testicular volume

exceeded 2.25 ml, a nonviable testicle was identified (sensitivity – 100.0 %, specificity – 73.0 %);

when the volume was less than 1.04 ml, viable undescended testes were found in all patients

(specificity – 100 %, sensitivity – 34 %). During quality assessment, the area under the ROC curve

reached 92.6 % indicating high predictive power of the model.
