A 34-yr-old female was diagnosed as being brain dead. Preoperative ultrasound revealed no abnormal focal lesions. However, the horseshoe kidney was identified during organ harvest. En bloc nephrectomy was performed. The kidney was divided at the midline of isthmus. The divided right kidney was discarded due to numerous arteries and veins. The divided left kidney was transplanted. After declamping, the kidney was well perfused and started clearing. Resistive index was 0.72. Glomerular filtration ratio was 84.69 mL/min on postoperative day 14. The horseshoe kidney can be successfully transplanted and could be a good solution for the shortage of organ donors.

PURPOSE: We estimated scattered radiation doses to the patients and medical practitioneer and revealed risk factors associated with increasing radiation doses during extracorporeal shock wave lithotripsy(ESWL). MATERIALS AND METHODS: At first, we measured radiation doses 2 times using thermoluminescence dosimeter to simulative patients and medical practitioneer without any shield during 10 minutes of ESWL and determined mean radiation dose/minute. From June to August 2007 at our institution, we prospectively measured radiation exposured time during respective ESWL for treatment of urinary stones. Thereafter, we calculated practical radiation doses to patients and medical practitioneer from respective mean radiation dose/minute. We also analyzed which factors were associated with increasing radiation doses. RESULTS: A total of 50 ESWL were analyzed from 38 patients. Mean radiation dose/minute to simulative patients and medical practitioneer was 16.20, 0.006mSv respectively. At 1 time ESWL, median radiation exposured time was 360 seconds(130-980), therefore, median radiation dose to patients and medical practitioneer was calculated as 97.20mSv(35.10-264.60), and 0.04mSv(0.01-0.08) respectively. Larger stone size had a correlation with increasing radiation dose and additional pain control group had higher radiation dose than otherwise. CONCLUSIONS: During ESWL, patients were relatively exposed to high radiation which were roughly corresponded to that of 3 times of computed tomography. But the radiation dose to medical practitioneer was insignificant consider international guideline. Medical practitioneer should be aware of radiation hazard and try to minimize radiation dose to the patients at the time of ESWL.

PURPOSE: We analyzed whether any problems existed in terms of the homogeneity of the Korean International Prostate Symptom Score (IPSS) questionnaire used in real practice. MATERIALS AND METHODS: Between July 2012 and August 2012, 48 Korean IPSS questionnaires used in real practice were collected. All the items on the questionnaire, including the quality of life (QoL) questions, were compared and we then determined the homogeneity of each question in comparison with the originally validated Korean version of the IPSS from 1996. RESULTS: Only 5 of 48 sources (10.4%) of the Korean IPSS totally corresponded with the original Korean version of the IPSS questionnaire. The consistency rate with the originally validated version was generally low for the answer choice items for each question, ranging from 16.6% for "less than half the time" to 35.4% for "almost always," with the exception of the item "not at all" (100.0%). The consistency rate was 60.4% for question 3 (intermittency) and 18.8% for question 6 (straining). No homogeneity was found in any of the QoL-related questions. The average consistency rate with the originally validated version was 42.2% and ranged from 22.9% for "unhappy" to the highest rate of 95.8% for "mostly satisfied." CONCLUSIONS: Compared with the originally validated Korean version of the IPSS, various Korean IPSS questionnaires used in real practice had significant problems in terms of homogeneity for both the questions and the answer choice items. Efforts are needed to ensure the uniform use of the validated Korean version of the IPSS questionnaire.

Spontaneously ruptured renal cell carcinoma (RCC) in end-stage kidney disease is very rare. Preoperative diagnosis is difficult because of the relatively small tumor size, associated hematoma, and surrounding acquired cysts. Two middle-aged men who were maintained on hemodialysis (HD) for over 10 years suddenly developed flank pain during HD. Computed tomography scans revealed an enhancing ruptured renal mass in one patient, and no obvious tumor lesion except for a hematoma in the other, both of which were later confirmed as RCCs by pathologic specimens.

PURPOSE: We investigated the effects of obesity on prostate volume (PV) and lower urinary tract symptoms (LUTS) in Korean men. MATERIALS AND METHODS: From December 2007 to 2009, a total of 10,383 ostensibly healthy Korean men aged > or =50 years visited our health promotion center for a routine check-up. Among them, 872 men who wanted a prostate evaluation were enrolled in this study. All men underwent detailed clinical evaluations with the International Prostate Symptom Score (IPSS) questionnaire. Anthropometric measurements, including height, weight, and waist and hip circumferences, were determined. A blood sample was obtained for serum prostate-specific antigen (PSA) measurement. Thereafter, a digital rectal examination and transrectal ultrasound were performed. RESULTS: In total, 465 men with moderate to severe LUTS (IPSS> or =8 points) were included in this prospective study. The participants' mean age was 57.2 years. Multivariate analysis demonstrated that only waist circumference was a significant factor in predicting PV besides age and serum PSA. The univariate analysis showed no statistically significant relations between any of the obesity-related parameters and LUTS. The PV was also not correlated with LUTS. CONCLUSIONS: Central obesity is the more important predictor of PV than overall obesity. There are no significant relations between obesity-related parameters and LUTS.

PURPOSE: The most serious complication of suprapubic cystostomy is bowel injury. By computed tomography (CT), we investigated the risk factors of possible bowel interposition through the percutaneous suprapubic cystostomy tract. MATERIALS AND METHODS: From September to October 2009, we consecutively reviewed 795 abdominopelvic CT scans of adult patients performed for various reasons in our hospital. From these scans, we selected the films wherein the urinary bladder was distended more than 6 cm above the symphysis pubis. We then determined whether the bowel was interposed between the bladder and the skin at the routine puncture site of suprapubic cystostomy (the midline of the abdomen 3 cm above the upper margin of the symphysis pubis). We analyzed which factors influenced the possibility of the bowel being interposed between the bladder and the skin at the suprapubic puncture site. RESULTS: A total of 226 CT (148 males, 78 females) scans were selected. The mean patient age was 63 years (range, 26-84 years). The mean distance between the upper margin of the symphysis pubis and the umbilicus was 14.4 cm (range, 7.2-21.0 cm). In the multivariate analysis, obesity, a positive history of radical pelvic surgery, and a short distance (< or =11 cm) between the symphysis pubis and the umbilicus had significant correlations with bowel interposition in the assumed tract. CONCLUSIONS: When performing a suprapubic cystostomy, extreme caution is needed to avoid possible bowel injury in patients who are obese, had a previous radical pelvic operation, or have a short distance between the upper margin of the symphysis pubis and the umbilicus.

Journal of Korean Medical Science 2022;37(31):e237-
Background:
Several cohort studies have explored the relationship between androgen deprivation therapy (ADT) and the severity of coronavirus disease 2019 (COVID-19). This study aimed to characterize the relationship between ADT and the severity of COVID-19 in patients with prostate cancer.
Methods:
A systematic search was conducted using PubMed, Embase, and Cochrane Library databases from the inception of each database until February 31, 2020. Patients with prostate cancer who were treated with ADT were assigned to treatment group while those patients who were not treated with ADT were assigned to the control group. Outcomes were severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) positivity, hospitalization, intensive care unit (ICU) admission, and death. The risk of bias was evaluated using ROBINS-I (Risk Of Bias In Non-randomized Studies of Interventions) tool.
Results:
Three studies with qualitative synthesis were included. Finally, two studies with quantitative synthesis having a total of 44,213 patients were included for the present systematic review. There was no significant difference in SARS-CoV-2 positive rate (odds ratio [OR], 0.52; 95% confidence intervals [Cis], 0.13–2.09; P = 0.362), hospitalization (OR, 0.52; 95% CIs, 0.07–3.69; P = 0.514), ICU admission (OR, 0.93; 95% CIs, 0.39–2.23, P = 0.881), or death (OR, 0.88; 95% CIs, 0.06–12.06; P = 0.934) between ADT and non-ADT groups.
Conclusion
Qualitative and quantitative analyses of previous studies revealed no significant effect of ADT on COVID-19. However, more studies with higher quality that explore biochemical and immunological factors involved are needed to confirm this finding in the future.

BACKGROUND AND OBJECTIVE: The long-term effects of beta-irradiation on intimal hyperplasia (IH) within the stented segment and vessel, and the lumen dimensions of non-stented adjacent segments, have not been sufficiently evaluated in patients with ISR. The long-term (24 months) effects of beta-irradiation ((188)Re-MAG3-filled balloon) were evaluated using intravascular ultrasound (IVUS) in patients with in-stent restenosis (ISR). SUCJECTS AND METHODS: A two-year follow-up IVUS was performed in 30 patients with patent ISR segments at the 6-monthly follow-up angiography. Serial IVUS images were acquired at 5 equidistant intra-stent sites and 3 different reference segment sites (1, 2 and 4 mm from stent margin). RESULTS: The mean intra-stent IH area and IH burden significantly increased between 6 and 24 months-from 2.1+/-1.1 to 2.6+/-1.4 mm2 (p<0.001) and from 26+/-10 to 33+/-14% (p<0.001), respectively. There were significant decreases in the mean external elastic membrane (from 10.1+/-3.9 to 9.7+/-3.9 mm2, p=0.015) and lumen area (from 5.6+/-2.3 to 5.1+/-2.3mm2, p=0.021) within the distal reference segments between 6 and 24 months. Target lesion revascularization (TLR) was performed between 6 and 24 months in 6 patients (20%) following the beta-irradiation therapy. There were no significant differences between the TLR and non-TLR groups, with the exception of a smaller minimum lumen CSA at 24 months in the TLR group. CONCLUSION: Because of a small amount of late loss between 6 and 24 months, most irradiated ISR vessel segments remained stable for up to 2 years. However, quantitative evidence of late catch-up was evident in most patients and was significantly associated with 24-month TLR in some patients with a smaller minimum lumen area.
