1. What statement considering the metabolic profiling using nuclear magnetic resonance (NMR) and mass spectrometry (MS) is incorrect?



1. Metabolomics aim to identify small molecules under physiological conditions that might serve as biomarkers and aid in the identification and treatment of health problems
2. Combining NMR and MS yields increased identification and quantification of compounds, especially in complexed ones
3. The combination of NMR and MS also allows the performance of isotope screening experiments and metabolic flow analysis (NMR provides quantification, and MS provides position)
4. Sarcosine, choline, phosphocholines, phosphorylcholines, carnitines, citrate, amino acids (lysine, glutamine, and ornithine), arachidonoyl amine, and lysophospholipids were found discriminative regarding the prostate cancer diagnosis
5. Threonine, phenylalanine, valine, isoleucine, lysine, methionine, leucine, glutamate, histidine, arginine, aspartic acid, tyrosine, glutamine, and serine were found discriminative regarding the bladder cancer diagnosis.

2. What statement considering the roboticassisted radical cystectomy (RARC) with totally intracorporeal urinary diversion (IUD) is wrong?



1. Early postoperative complications (0~30 days) were statistically higher in elderly patients (aged ≥75 years) compared to younger patients (aged <75 years)
2. Late postoperative complications (30~90 days) and late readmission rate were statistically homogeneous between <75yearold and ≥75yearold patients
3. ASA score was found the only independent predictive factor of late postoperative complications
4. No statistically significant difference in terms of Cancerspecific mortality and overall mortality was found between <75yearold and ≥75yearold patients
5. In experienced hands, RARC with IUD can be safely applied to ≥75yearold patients, without affecting the complications ratio and the oncological and functional outcomes.

3. According to the prospective cohort study by Keiichiro Hayashi et al., the most pulse wave velocity (PWV) decrease at which time point after longterm administration of tadalafil (5 mg/d)?



1. 6 weeks
2. 12 weeks
3. 24 weeks
4. 36 weeks
5. 48 weeks

4. What statement considering the impact of environmental fine particles on male infertility is incorrect?



1. Particulate matter 2.5 (PM2.5), referring to fine air particles with a diameter of <2.5 μm, can enter the respiratory system and lodge in different organ systems
2. Although not statistically significant, the average 24month PM2.5 concentration had a negative effect on sperm count and concentration in infertile Taiwanese men
3. The effect of PM2.5 on sperm motility and morphology was minimal
4. BMI, not PM2.5, was observed to be an independent factor predicting lower total sperm count and serum testosterone in infertile Taiwanese men
5. All statement is correct.


Urol Sci 2019;30(4):177-183.

5. What statement considering the Polyorchidism is wrong?


1. Triorchidism (three testes) is the most common form of polyorchidism
2. Most supernumerary testes are located in the left side scrota region
3. According to the metaanalysis by Bergholz et al. in J. Urol., polyorchidism is associated with an increased risk of malignancy and torsion
4. According to the Bergholz classification, Type B polyorchidism could be drained by outflow path (vas deferens)
5. The supernumerary testis usually has similar echogenicity and vascular flow to those of the normal testis.
