Comparative analysis of artificial intelligence chatbot recommendations for urolithiasis management: A study of EAU guideline compliance.

OBJECTIVES: Artificial intelligence (AI) applications are increasingly being utilized by both patients and physicians for accessing medical information. This study focused on the urolithiasis section (pertaining to kidney and ureteral stones) of the European Association of Urology (EAU) guideline, a key reference for urologists. MATERIAL AND METHODS: We directed inquiries to four distinct AI chatbots to assess their responses in relation to guideline adherence. A total of 115 recommendations were transformed into questions, and responses were evaluated by two urologists with a minimum of 5 years of experience using a 5-point Likert scale (1 - False, 2 - Inadequate, 3 - Sufficient, 4 - Correct, and 5 - Very correct). RESULTS: The mean scores for Perplexity and ChatGPT 4.0 were 4.68 (SD: 0.80) and 4.80 (SD: 0.47), respectively, both significantly differed the scores of Bing and Bard (Bing vs. Perplexity, P<0.001; Bard vs. Perplexity, P<0.001; Bing vs. ChatGPT, P<0.001; Bard vs. ChatGPT, P<0.001). Bing had a mean score of 4.21 (SD: 0.96), while Bard scored 3.56 (SD: 1.14), with a significant difference (Bing vs. Bard, P<0.001). Bard exhibited the lowest score among all chatbots. Analysis of references revealed that Perplexity and Bing cited the guideline most frequently (47.3% and 30%, respectively). CONCLUSION: Our findings demonstrate that ChatGPT 4.0 and, notably, Perplexity align well with EAU guideline recommendations. These continuously evolving applications may play a crucial role in delivering information to physicians in the future, especially for urolithiasis.

Micro-RNA-371a-3p in Germ Cell Testicular Tumors on Diagnosis: A Prospective Case-Control Study in Turkish Population.

PURPOSE: We aimed to evaluate the diagnostic sensitivity and specificity of the miRNA-371a-3p for the primary diagnosis of germ cell tumors (GCT) and to investigate its relationship with pathological factors and clinical stage in the Turkish population. MATERIALS AND METHODS: In this prospective study, a total of 60 patients with GCTs, and 40 healthy male controls were examined for serum levels of miRNA-371a-3p before orchiectomy and again two weeks after surgery. The miRNA-371a-3p, alpha-fetoprotein (AFP), and beta-human chorionic gonadotropin (bHCG) levels in the preoperative and postoperative periods were compared at different clinical stages. Receiver operating characteristics curve analyses were performed to determine the sensitivity and specificity of miRNA-371a-3p. Clinical and pathological factors such as clinical stage (CS), tumor size, histology, rete testis invasion, and lymphovascular invasion, potentially impacting miRNA-371a-3p expression levels (relative quantity, RQ), were evaluated statistically. RESULTS: The sensitivity of miR-371a-3p in GCT patients was 98.3%, and the specificity was 95% (AUC = 0.997 [95%Cl:0.99-1], p < .001). miR-371a-3p expression was not detected in two patients with teratoma. The median miR-371a-3p RQ was 489 times in GCT and 2.2 times in the Control group (p < .001). In the postoperative period, there was a significant decrease in AFP and bHCG levels in all CS-1 (p = .01) and 30% of the other CS (p = .3). Throughout this time there was a decrease of 19 times at the miR-371a-3p RQ in CS-1(p < .001) and 1.6 times in the other CS (p < .001). The miR-371a-3p RQs were correlated with tumor size and CS. CONCLUSION: The miR-371a-3p seems to have higher diagnostic accuracy than classical serum tumor markers in GCT.

Observation and comparison of gas formation during holmium:YAG laser lithotripsy of cystine, uric acid, and calcium oxalate stones: a chromatographic and electron microscopic analysis.

The primary aim of the present in vitro study is to analyze the chemical content of the bubbles occurring during the fragmentation of cystine stones with both the high-power and low-power holmium:YAG (Ho:YAG) lasers. The secondary aim is to discuss their clinical importance. Three types of human renal calculi calcium oxalate monohydrate (COM), cystine, and uric acid were fragmented with both low-power and high-power Ho:YAG lasers in separate experimental setups at room temperature, during which time it was observed whether gas was produced. After laser lithotripsy, a cloudy white gas was obtained, after the fragmentation of cystine stones only. A qualitative gas content analysis was performed with a gas chromatography-mass spectrometry (GC-MS) device. The fragments in the aqueous cystine calculi setup were dried and taken to the laboratory to be examined by scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) and X-ray diffraction analysis. No gas production was observed after fragmentation in the COM and uric acid stones. Free cystine, sulfur, thiophene, and hydrogen sulfide gas were produced by both low-power and high-power Ho:YAG laser lithotripsy of the cystine stones. In the SEM-EDX mapping analysis, a free cystine molecule containing 42.8% sulfur (S), 21% oxygen (O), 14.9% carbon (C), and 21% nitrogen (N) atoms was detected in the cystine stone experimental setup. The evidence obtained, which shows that hydrogen sulfide emerges in the gaseous environment during Ho:YAG laser fragmentation of cystine stones, indicates that caution is required to prevent the risk of in vivo production and toxicity.

Female urinary incontinence on TikTok and YouTube: is online video content sufficient?

INTRODUCTION AND HYPOTHESIS: The objective of the study is to evaluate the reliability and quality of the most-viewed female urinary incontinence-related TikTok and YouTube posts. Our second goal is to analyze the differences in the quality and content of videos between these platforms. METHODS: We searched for the keyword "female urinary incontinence" on TikTok and YouTube on 1 March 2023. We sorted the videos that appeared out of searches for this keyword by "top" results on TikTok and by "relevance" on YouTube. We excluded the videos that were not in English, whose narrator was unclear, unrelated videos, advertising videos, and duplicate videos. In this study, we included the top 50 videos on both platforms that were directly related to female urinary incontinence. The characteristics of the videos, such as likes, video duration, views, and type of narrator (patient, physician, nonphysician practitioner, and health care company), and DISCERN scores were analyzed. RESULTS: We observed that the median view count (p<0.001) and the median video duration (p<0.001) were higher and longer respectively on YouTube than on TikTok. In addition, the median DISCERN score of these videos was higher on YouTube than on TikTok (p<0.001). Similarly, the overall quality of videos was higher on YouTube than on TikTok (p=0.002). Only in two TikTok and two YouTube videos have the narrators cited a reference. CONCLUSIONS: Our findings emphasize the present lack of high-quality content available on TikTok and YouTube from both health care and nonhealth care experts. To address this lack of information, health care providers, especially urologists, should take an active role in creating video content.

A retroperitoneal myopericytoma: The first case located at the retroperitoneal area and not originate from the kidneys.

A 25-year-old woman had a mass of approximately 65 cm × 33 cm × 102 cm, located in the left paraaortic area on CT scan. It was diagnosed as retroperitoneal malignant neoplasm on imaging. Afterward, open retroperitoneal tumor excision was performed. At laparotomy, the mass was carefully dissected from the ureter, renal artery, and aorta and excised as en-bloc. The pathological result was "myopericytoma." Histologically, the pathological findings characterized a pericytic neoplasm characterized by a perivascular growth of myoid tumor cells. In addition, there were uniform, oval-shaped cells with eosinophilic cytoplasm arranged in short fascicles around blood vessels. The cytologic atypia and mitoses were absent. There are many different tumors in the retroperitoneal area. Most of these lesions are malign nature. Nevertheless, for each benign and malign neoplasm, the preoperative imaging method is generally similar. This present case showed the significant findings of myopericytoma, a benign pathology located in the retroperitoneal area.

Influencing factors of acute kidney injury following retrograde intrarenal surgery.

PURPOSE: To investigate the influencing factors of acute kidney injury (AKI) following retrograde intrarenal surgery (RIRS). METHODS: The data of patients who underwent RIRS for kidney stones between January 2018 and June 2022 at two tertiary centers were retrospectively analyzed. Demographic data of patients were obtained. According to kidney disease: Improving Global Outcomes (KDIGO) criteria, those with and without AKI were divided into two groups. Preoperative, intraoperative, and postoperative predictive factors of patients were investigated between the groups. In addition, the influencing factors of AKI were examined by multivariate analysis. RESULTS: This study included 295 (35.7%) women and 532 (64.3%) men. The mean age was 50.03 ± 15.4 years (range 18-89), and mean stone size was 15.5 ± 6.1 mm (range 6-47). Overall, 672 of patients (81.3%) were stone-free after the initial treatment. According to KDIGO, 110 of patients (13.3%) had AKI during the postoperative period. Univariate analysis showed that stone size (P = .003), previous stone surgery (P = .010), renal malformations (P = .017), high operative time (P = < .001), high preoperative creatinine value (P = .036), intraoperative complications (P = .018), and postoperative urinary tract infection (P = .003) had significant influence on the AKI after RIRS. Multivariate analysis excluded previous stone surgery, high preoperative creatinine value, renal malformations, and intraoperative complications from the logistic regression model, whereas other factors maintained their statistically significant effect on AKI, indicating that they were independent predictors. CONCLUSIONS: Stone size, operative time, postoperative urinary tract infection, and diabetes mellitus are significant predictors of AKI. During RIRS, urologists should consider the factors that increase the risk of AKI and evaluate the treatment outcomes based on these factors.

Depictions of penises in historical paintings reflect changing perceptions of the ideal penis size.

OBJECTIVES: To investigate alterations in depicted penis size by evaluating nude male paintings from the 15th to 21st centuries. MATERIALS AND METHODS: Nude-male paintings were identified from various art history websites and analysed to determine changes in penis size over time. Two observers organised the paintings according to the century in which they were created and made the calculations. Penile length to ear length (PtEL) or penile length to nose length (PtNL) were calculated to standardise the measurements using professional image analysis software. PtEL was first attempted for all paintings; if PtEL could not be ascertained, then nose length was used instead of the ear, as the nose length is defined as equal to ear length according to the golden ratio. Thus, PtNL was ensured and both ratios were then referred to using a common term: penis depiction ratio (PDR). Further analysis was performed by dividing the paintings into three groups according to the historical development of art: Renaissance Period (1400-1599; 15th-16th centuries), Baroque-Rococo and Impressionism Period (1600-1899; 17th-19th centuries) and Contemporary Art Period (1900-2020; 20th and 21st centuries). RESULTS: Of 232 identified paintings, 72 (31.1%) were excluded because they depicted images of adolescents or an erect penis. The PDR was found to differ significantly between paintings created in different centuries (P < 0.001). Subgroup analysis revealed that paintings from the 21st century demonstrated significantly higher PDRs than paintings from previous centuries (P = 0.001). CONCLUSIONS: In paintings depicting nude males, the size of the penis has gradually increased throughout the past seven centuries, and especially after the 20th century. This observation illustrates the changing sociocultural inputs into male body image and emphasises the need for improved understanding of the sociocultural factors associated with the perception of penis size in men.

Digitalization and Urological Diseases: Severity of Cyberchondria and Level of Health Anxiety in Patients Visiting Outpatient Urology Clinics.

This study aimed to evaluate the cyberchondria levels of patients who applied to the urology outpatient clinic. The second goal of this study was to evaluate the relationship between cyberchondria severity and health anxiety in these patients. The present prospective observational study was conducted at the urology outpatient clinic of two tertiary centers in our city between September and December 2021. Eligible patients were the adult patients (>18 and ≤60 years) who used the Internet for health purposes and had no self-reported psychological or mental disease. The patients were divided into following groups according to their complaints: general urology, uro-oncology, andrology, functional urology, and endourology (stone disease). The level of cyberchondria and health anxiety was evaluated for these patients by using the Short Health Anxiety Inventory (SHAI) and a short-form version of the Cyberchondria Severity Scale (CSS-12). This study enrolled 578 patients (190 female, 388 male). The mean age of patients was 43.4 ± 13.3 years (18-60 years). The mean CSS-12 was 28.1 ± 12.1, and the mean value of SHAI was 18.9 ± 13.6. The patients had andrological symptoms, is uniquely related to higher CSS and health anxiety, and followed by uro-oncological diseases. However, the least relationship was observed in patients with functional urological diseases (analysis of variance [ANOVA], p < 0.001 for CSS-12; p < 0.001 for SHAI). In addition, a positive correlation was observed between the CSS and SHAI (Pearson's correlation = 0.782). The increased level of cyberchondria causes increased health anxiety and an increased disease burden in these patients. Therefore, physicians should consider this increased treatment burden during the treatment of patients.

The Role of Acidic Urine on Detrusor Pressure in Patients with Overactive Bladder: A Urodynamic Evaluation.

OBJECTIVES: To evaluate the relationship between urine pH value and urodynamic parameters in patients with overactive bladder. METHODS: The patients' data whose underwent standard urodynamic study at two tertiary centers in our city. The period between January 2015-January 2021 was reviewed retrospectively. The inclusion criteria were the patients with overactive bladder, over 18 years of age, and with urine analysis before urodynamic study. Patients were divided into two groups as those with acidic urine pH (Group 1) and without (Group 2). The detrusor pressures obtained from filling cystometry were compared between the groups. In addition, the correlation between detrusor pressure and urine pH was examined. RESULTS: The data from 211 patients (109 females, 102 males) were analyzed during the screening period. Eighty-two patients were in Group 1 and 129 patients in Group 2. The mean age was similar between the groups (p = 0.244). The bladder volume at first sensation of filling and urodynamic maximal bladder capacity was lower in Group 1 than Group 2 (p = 0.004; p < 0.001, respectively). The maximum detrusor pressure was higher in the acidic urine pH group (Group 1, 55.8 ± 20.6) than non-acidic urine pH group (Group 2, 14.5 ± 10.2), and it was statistically significant (p < 0.001). In addition, a significant negative correlation was observed between urine pH level and detrusor pressure (p < 0.001). CONCLUSIONS: The presence of acidic urinalysis is associated with many urodynamic findings. Significantly, the patients with detrusor overactivity had more acidic urine than without detrusor overactivity. Therefore, for patients with high detrusor pressure, urinalysis should be evaluated carefully.

Significantly, the patients with detrusor overactivity had more acidic urine than without detrusor overactivity. Therefore, for patients with high detrusor pressure, urinalysis should be evaluated carefully (AU)

Testicular volume loss in the long-term follow-up after surgical detorsion of the testis.

AIM: The aim of this study is to evaluate sonographic testicular volume of patients who underwent surgical detorsion due to testicular torsion and to reveal the frequency of long-term testicular volume loss and the factors affecting it. METHOD: The files of patients who underwent surgical detorsion due to unilateral testicular torsion in our hospital between 2011 and 2019 were reviewed retrospectively. Age at the time of detorsion surgery, time from the onset of pain to surgery, degree of torsion, and ultrasonographic testicular volumes before detorsion were noted. Afterward, patients with at least 6 months of follow-up were contacted by phone and testicular volumes were measured by scrotal ultrasonography (US). The sonographic formula Length × Width × Height × 0.72 was used to determine testicular volumes. RESULTS: There were 97 patients who underwent surgical detorsion within the given time frame. However, 43 of these patients accepted to be involved in the study and a follow-up scrotal US was performed. The mean age at the time of detorsion was 13.6 ± 5.6 years, whereas it was 16.7 ± 6.2 years at the time of the follow-up visit. The median time from the onset of pain to surgery was 4 h (range 1-36 h). In the preoperative US, the mean volume of the affected testis was 10.8 ± 5.6 mm3, while the mean contralateral testis volume was 10.2 ± 5.4 mm3 (p = 0.134). The median follow-up time in our study was 24 months (range 6-96 months). In the control US, the mean volume of the affected testis was 9.5 ± 7.1 mm3, while the mean volume of the contralateral testis was 14.4 ± 9 mm3 (p = 0.001). The affected testicular volumes decreased in 23 patients (range 1.1-100%), there was no change in testicular volumes in two patients, and there was an increase in testicular volumes in 18 patients (range 3.8-100%). In the ROC analysis, risk of testicular volume loss can be predicted with 87.5% sensitivity and 83.9% specificity when the time from the onset of pain to surgery exceeds 5.5 h (AUC = 0.904). CONCLUSION: Our results indicated that if the time from the onset of pain to surgery exceeds 5.5 h, the testicular volume loss may be expected in the long term. Thus, patients and parents should be informed accordingly.

Through the zipper or pants down: Does it change uroflowmetry parameters in healthy males?

OBJECTIVE: To evaluate if voiding through the zipper or voiding pants down would make any difference with regard to uroflowmetry parameters and postvoiding residual urine (PVR) volumes in healthy males with no lower urinary tract symptoms (LUTS). METHODS: Healthy males over 18 years of age with no LUTS were prospectively evaluated using a uroflowmetry test. Each individual was asked to void through the zipper (group 1) and pants down (group 2) at different times. The uroflowmetry test was repeated if the voided volume did not exceed 150 mL. Uroflowmetry results such as voided volume, maximum flow rate (Qmax), average flow rate (Qave), and duration of voiding were noted. PVR volume was assessed using ultrasonography. Electromyography was not used. Data are shown as mean ± standard deviation. For statistical analysis, a paired t test was used to analyze parametric parameters. RESULTS: A total of 44 males were enrolled. The median age of the individuals was 24 (range 18-44 years). There were no statistically significant differences between the two measurements in terms of voided volume (307 ± 121 mL vs 325 ± 145 mL, P = .365) and duration of voiding (25 ± 11 s vs 23.8 ± 11.6 s, P = .526). However, there were statistically significant differences in Qmax (26.6 ± 6.7 mL/s vs 30.0 ± 8.2 mL/s, P = .001), Qave (14.4 ± 3.6 mL/s vs 16.2 ± 5.1 mL/s, P = .009), and PVR volumes (23.9 ± 19.4 mL vs 3.9 ± 9.6 mL, P = .0001). CONCLUSION: Voiding pants down shows higher flow rates and lower PVR than voiding through the zipper in individuals with no LUTS. Future studies with a larger number of individuals (including those with LUTS) and a broader age range cohort are required for solid conclusions.

The role of prostate inflammation in the pathogenesis of urethral strictures occurring after transurethral resections.

OBJECTIVE: To make an extensive evaluation about the effects of histopathological findings acquired from the resection materials of patients who underwent transurethral resection of prostate (TUR-P) due to benign prostate hyperplasia (BPH) on postoperative urethral stricture formation. MATERIALS AND METHODS: Among patients who had TUR-P due to BPH and were followed up for minimum 6 months, 51 patients detected to have urethral stricture based on endoscopic imaging were included in the urethral stricture group (Group 1) and 52 patients without urethral stricture were included in the control group (Group 2). The relation between histopathological findings of TURP materials and postoperative stricture occurrence was investigated. RESULTS: No difference in age, prostate volume, operation time and postoperative catheterization time was detected among the groups (p=0.86, p=0.13, p=0.06, p=0.32, respectively). Average time until the urethral stricture diagnosis in the group with urethral stricture was measured as 57.9±27.2 days. In our study, inflammation intensity in peri-urethral, stromal and periglandular areas and intraglandular destruction ratios were higher in urethral stricture group (Group 1) (p=0.048, p=0.3, p=0.03, p=0.01, respectively). Again, it was detected that neutrophil, plasmocyte and eosinophil cell ratios were higher in peri-urethral, stromal and periglandular areas and lymphocyte values were lower compared to the control group. CONCLUSION: Acquired data has shown that acute inflammatory attacks may be related to urethral stricture with a mostly chronic inflammation background in the prostate. During histopathological examination of prostate tissue acquired through TURP, especially high peri-urethral neutrophil, plasmocyte and eosinophil cell ratios and intra-glandular destruction ratios are important for predicting postoperative urethral stricture occurrences.

Effect of SARS-CoV-2 infection on semen parameters.

INTRODUCTION: In this study, we aimed to assess the effect of SARS-CoV-2 infection on semen parameters in one group of patients before and after infection. METHODS: Patients were screened if they had a semen analysis performed between October 1, 2019, and December 1, 2020, in the assisted reproduction unit and later had positive polymerase chain reaction (PCR) test for SARS-CoV-2 infection. The patients' semen parameters were recorded before and after SARS-CoV-2 infection, along with degrees of SARS-CoV-2 infection, dates of SARS-CoV-2 infection, durations between the treatment for SARS-CoV-2 infection and the second semen analysis, time of symptom onset, duration of their symptoms, ages, comorbidities, and any medications patients were taking. RESULTS: Forty-one patients were included in the study. The mean age of the patients was 31.29±5.95 years. The mean duration from first semen analysis to the PCR test was 7.74±3.03 months. The mean duration between the PCR test and later semen analysis was 2.35±1.35 months. The median sperm concentration for the patients before and after SARS-CoV-2 infection were 24 mil/ml and 13 mil/ml, respectively (p<0.001). The normal morphology percentage before infection was 3.16±0.92, while it was 2.44±1.04 after infection (p=0.011). In 26 patients, the period from the time of infection to the second semen analysis was over 70 days, while this period was less than 70 days in the other 15 patients. In both patient groups, a significant decrease was detected in the sperm concentrations and total sperm count. CONCLUSIONS: In the semen samples we assessed, we observed a significant decrease in the mean sperm concentration, total sperm count, and mean percentage of samples with normal morphology after SARS-CoV-2 infection.

Can Urinary KIM-1 and NGAL Predict Management Endoscopic Surgery in Acute Unilateral Obstructive Stone Disease? Results from a Prospective Cohort Study.

INTRODUCTION: Kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) are the leading novel biomarkers used efficiently in acute kidney injury (AKI). The levels of these biomarkers increase especially in the early period of nephrotoxic and ischemic renal damage. In this study, we aimed to investigate the clinical importance of NGAL and KIM-1 biomarkers used in the effective evaluation of kidney functions in patients with acute unilateral obstructive stone disease (AUOSD) in the management of endoscopic surgery. MATERIALS AND METHODS: We prospectively included patients who underwent endoscopic surgery due to AUOSD between January 2018 and December 2019. Urine KIM-1 and NGAL values of the patients were measured preoperative period, postoperative 4th h, and postoperative 7th day. The patients were evaluated according to the location and size of the stone, the degree of renal hydronephrosis, the duration of the operation, complications, and JJ stent placement. RESULTS: The study enrolled 50 patients. Urinary KIM-1/Cr and urinary NGAL/Cr ratios were higher in postoperative 4th h than in others (p < 0.001). Also, we found that urinary KIM-1/Cr and urinary NGAL/Cr ratios with Grade 2 and higher hydronephrosis were statistically higher than Grade 0-1 hydronephrosis (p < 0.001 and p: 0.042, respectively). Additionally, a preoperative urinary KIM-1 value of 1.24 ng/mL had a sensitivity of 78% and a specificity of 63% to predict the presence of hydronephrosis. When urine KIM-1 and NGAL results were compared with surgery time, stone size and location, serum creatinine (sCr) value, and Post-Ureteroscopic Lesion Scale grade, the difference was not statistically significant. Postoperative 7th day NGAL/Cr and KIM-1/Cr ratios were statistically higher in those with JJ stents placed (p: 0.03 and p: 0.004, respectively). CONCLUSION: KIM-1 and NGAL can be used in our assessment of renal function in patients with AUOSD, even if sCr is normal. Also, these biomarkers can predict the presence of hydronephrosis. It can be helpful in determining the time of surgical treatment, as well as providing information in the follow-up of patients with JJ stents after treatment.

Correlation between Twitter mentions and academic citations in sexual medicine journals.

Social media services, especially Twitter, are used as a commonly sharing tool in the scientific world. This widespread use of Twitter would be an effective method in spreading academic publications. So, we aimed to investigate the relationship between Twitter mentions and traditional citations of articles in sexual medicine journals in this study. We reviewed the articles published in seven journals of sexual medicine (2 years after the publication of the articles) between January 2018 and June 2018. In the first half of 2018, 410 articles were extracted. Of these, 352 (85.9%) were original articles, while 58 (14.1%) were review articles. The median number of citations of the articles mentioned at least once on Twitter was 7 (interquartile range: 0-111) for Google Scholar, whereas it was 0 (interquartile range: 0-63) for Scopus, respectively. It was 4 (interquartile range: 0-25) for Google Scholar and 0 (interquartile range: 0-7) for Scopus. The publications mentioned on Twitter were cited more than the non-mentioned publications in the traditional-based citation system (p < 0.001). A significant relationship between the citation numbers and tweet numbers was also observed (p < 0.001). Also, in the linear regression model, the tweet numbers (p < 0.001) and article types (p < 0.001) were found to be related to the Google Scholar citation numbers. In conclusion, using Twitter as a professional tool in academic life would allow information to be propagated and responded quickly, especially for sexual medicine journals.

The Benign Renal Masses that Were Exposed after Nephron-Sparing Surgery: "Postsurgical Fatty Tumor." Is It Related to the Surgical Technique?

After nephron-sparing surgery (NSS), postsurgical fatty tumor could be mistakenly reported as angiomyolipoma during radiologic imaging of some patients. In the present paper, we studied the postsurgical fatty tumor detected after NSS but not covered before in the literature. In addition, we also evaluated whether the postsurgical fatty tumor was related to the surgical technique employed. Patients admitted to the urology department of our university hospital from 2014 to 2019 and operated with open NSS were evaluated retrospectively. We detected those 156 patients were operated with NSS. Nine patients with angiomyolipoma as primary pathology and four patients with surgical border positivity were excluded from the study. The patients were divided into two groups based on the repair of tumor extraction region. In Group 1, fatty tissue was used for repair, and Group 2 is the primary repair group. In all, 143 patients (Group 1 = 79, and Group 2 = 64) were included in the study. No demographic and radiologic differences, such as number of patients, age, gender, positioning of tumor, mass localization, tumor diameter, and RENAL nephrometry scoring system, were detected between the two groups. Postsurgical fatty tumors were detected in 28 patients in Group 1 and in two patients in Group 2 (P < 0.001). In patients with negative surgical margins after partial nephrectomy, lesions that were radiologically detected mimicking as angiomyolipoma were defined as "postsurgical fatty tumor." This mass containing adipose tissue only neither depicted vascularization and enhancement nor increase in size for at least 1 year. We assumed that these lesions must be followed as benign lesions not requiring additional treatment.

A rare variant Klinefelter syndrome seen 40 years later: 47,X,del(Xq24),Y.

Patients with Klinefelter syndrome (KS) show a typically 47,XXY karyotype; however, some variations have been observed, including 47,XX,der(Y), 46,XY/47,XXY, 48,XXXY, 48,XXYY, and mosaicism or structural sex chromosome abnormalities in some patients. In the literature, a rare KS variant, 47,X,del(Xq),Y karyotype, was reported in only a few cases prior to 1981. A 40-year-old man (IV-3) was referred to our department due to infertility. His phenotype did not differ from the classic KS phenotype. He had two siblings (1-male; 1-female). His brother (IV-5) had mental retardation and died one year earlier at age 32. Additionally, his sister (IV-2) also had a history of infertility due to her husband's azoospermia. His mother had a history of 12 miscarriages. Karyotype analysis revealed the 47,X,del(Xq24),Y karyotype, and no deletions were seen in the AZF and SRY regions. We thought this chromosomal abnormality in the patient might have resulted from X-autosome translocation in one of his parents since his mother had recurrent pregnancy loss and his sibling had mental retardation. However, we could not confirm it due to his parents were not alive. This study shows the first case of a long-arm X-chromosome deletion after a long period and reviews current knowledge concerning variant KS (deletion Xq).

Is Retrograde Intrarenal Surgery as Safe for Children as It Is for Adults?

INTRODUCTION: The primary aim of this study is to compare the efficacy and safety of retrograde intrarenal surgery (RIRS) among the children and adults with similar stone burdens and locations. Also, the secondary aim of this study is to identify the factors affecting the stone-free rates (SFRs) of RIRS. METHODS: We retrospectively compared perioperative results, SFRs, and complication rates (CRs) between pediatric (group 1, n: 55) and adult (group 2, n: 220) age groups diagnosed with kidney stones and treated by flexible ureterorenoscopy using the same instruments. Furthermore, multivariate analysis was performed to determine the factors affecting the SFR. RESULTS: A total of 275 patients (pediatric group: 55; adult group: 220) were included in this study. The mean age of pediatric and adult groups was 7.2 ± 5.3 and 43.9 ± 15.1, respectively. The mean stone size was 13.9 ± 6.6 mm in the pediatric group compared to 14.8 ± 6.7 mm in the adult group (p = 0.35). Stone localizations and number were similar. JJ stenting for passive dilatation and use of UAS were higher in the pediatric group (p = 0.002; p = 0.017). However, postoperative double pigtail stenting rate was higher in the adult group (p < 0.001). Total CR was 13.8% and mostly Clavien I-II, and no difference was observed between the 2 groups (p = 0.541). The SFRs between the groups were similar (pediatric group: 81.8%; adult group: 78.2%; p = 0.554). On multivariate analysis, stone size (p < 0.001) and lower calyx stone (p < 0.001) were the negative predictive factors for SFR. CONCLUSION: There are small technical differences between pediatric patients and adult patients in our study, but RIRS in children is as safe and efficient as it is in adults.
