Post-traumatic renal arteriovenous malformation failed endovascular embolization.

Renal arteriovenous malformations (AVMs) are abnormal connections between the renal arteries and venous system. Arteriovenous fistulas account for 70%-80% of renal arteriovenous abnormalities, often resulting from iatrogenic injuries. While most renal AVMs are asymptomatic, hematuria is a common symptom caused by AVM rupture into the renal calyces. Angiography is the gold standard for diagnosis, but noninvasive imaging techniques like ultrasound, computed tomography, or magnetic resonance imaging are commonly used for initial evaluation. Most renal AVMs are managed conservatively. Symptomatic patients typically undergo endovascular embolization, the preferred treatment, while surgery is reserved for unstable patients or those with complex vascular anatomy. We present a case of a 32-year-old man with renal AVMs following a motor vehicle accident. The patient initially received unsuccessful endovascular embolization but achieved successful treatment through open fistula ligation. This case highlights the challenges in managing renal AVMs and the importance of considering alternative interventions when initial treatments prove ineffective.

Predictors of forniceal rupture in patients with obstructing ureteral calculi: Analysis of multicenter data.

Background: Renal forniceal rupture (FR) is a unique complication of obstructive uropathy. This study aimed to identify the predictors of FR among patients presenting with renal colic due to obstructing ureteral calculi. Materials and Methods: After obtaining ethics approval, electronic records of patients from three National Guard hospitals in Saudi Arabia were reviewed between 2016 and 2020 to identify patients who presented with renal colic and were diagnosed with FR due to obstructive ureteric stones (FR group). An equivalent number of consecutive patients presenting with renal colic due to obstructing ureteric stones without FR was selected as a control group (non-FR group). Patients were grouped according to age group (<30, 30-40, 41-50, and >50 years), body mass index (BMI) class, gender, comorbidities, grade of hydronephrosis, location of the stone in the ureter, size of the stone (<3 mm, 3-7 mm, and >7 mm), and stone former status. Baseline patients' and stone characteristics were compared, and a regression analysis was performed to identify predictors of FR. Results: A total of 50 patients with FR were identified, and a control group of 50 patients without FR were selected. The baseline patients' and stone demographic characteristics in terms of age (P = 0.42), gender (P = 0.275), BMI (P = 0.672), comorbidity, grade of hydronephrosis (P = 0.201), and stone location (P = 0.639) were comparable between the FR group and the non-FR group. However, the stone size was statistically significant between both groups (P = 0.014). On multivariable analysis, it was found that the stone size was associated with a significantly higher increase in the incidence of FR (odds ratio [OR]: 6.5 [1.235-34.434]; P = 0.027). Furthermore, the age group between 30 and 40 years was potentially at a lower risk for FR (OR: 0.262 [0.069-0.999]; P = 0.049). Conclusion: This multicenter study showed that the stone size 3-7 mm had a six-fold increase in the chance of FR, and the age group between 30 and 40 years is potentially at a lower risk for FR.

Mixed primary and secondary vaginal calculi: a case report.

Vaginal calculi are classified according to the pathogenesis of calculus formation. Primary and secondary vaginal calculi. In this article, we present an interesting case that we believe to be a mixed primary and secondary vaginal calculi in which both originated as a result of a vesicovaginal fistula (VVF) and stitches found in the vagina. Although vaginal calculi are a rare disease, a high index of suspicion is needed, especially in patients with a history of gynecological procedures. Since the high recurrence rate of VVF along with its complications, more frequent follow-up and physical examination are required to avoid the recurrence of the disease.

Empirical therapy for male factor infertility: Survey of the current practice.

BACKGROUND: Empirical therapy is sometimes used by urologists who desire to improve the outcomes for infertility patients. However, the literature on empirical therapies is scarce. Therefore, we aimed to assess the clinical practice of urologists regarding the use of empirical therapy in the treatment of infertility patients. METHODOLOGY: An online survey using Google Forms was used to collect data during the Saudi Urological Association Annual Meeting, February 2019. Additional data were gathered electronically in March and April 2019 and sent to respondents. The study was closed in May 2019. No incentives were provided to the respondents. RESULTS: A total of 96 (80%) urologists participated in the survey, of whom 69.8% were consultants, and 20.8% were andrology-trained urologists. Empirical therapy was used by 86.5% of urologists for patients with idiopathic oligoasthenoteratozoospermia. The most commonly used empirical therapies were zinc, L-canitine, clomiphene citrate, and L-arginine. The main factors that influenced the selection of empirical therapy were follicle-stimulating hormone, total testosterone, and luteinizing hormone levels. CONCLUSION: Empirical therapy was used by more than three-quarters of the participants for idiopathic male infertility. There were no clear guidelines for the ideal therapy to be considered for individual patients while treating empirically. Our concern is that urologists use a wide variety of medications without significant data to support these medications.

Current surgical procedures for benign prostatic hyperplasia and impression of new surgical modalities.

BACKGROUND: Surgery is considered the most effective treatment for Benign prostatic hyperplasia (BPH) and Transurethral resection of prostat (TURP) is considered the gold standard. The goal of this study is to assess the surgical interventions used in Saudi Arabia, the difference in surgical procedures done depending on age and years of experience and the participant's impression on the new modalities in the management of BPH. METHODOLOGY: An online survey using Google Forms was sent to the participants. The data were collected during Saudi Urological Association Annual Meeting February 2019. Additional data were gathered 2 months later. The study was closed in May 2019. No incentives were provided to participants. RESULTS: A total of 65 (54.1% response rate) urologist participated in the survey, of whom 41.5% of respondents were aged <40 years, while 40% of them aged between 40 and 60 years. Forty-seven (72.3%) out of 65 were consultants. The essential investigations used by most participants prior to surgical interventions are prostate specific antigen, urine culture, urinalysis, and abdominal ultrasound. The most used surgical interventions are unipolar transurethral resection (TURP), Bipolar TURP, and open prostatectomy. About 50% of respondents preferred open prostatectomy for prostate size above 100 g. In general, 40%-50% of participants believe that urethral lift, Rezum, Aquablation, prostate artery embolization, and robotic simple prostatectomy are useful options. CONCLUSION: TURP continues to be the main intervention for prostate sizes <100 g. Open prostatectomy is widely used intervention for prostate sizes more than 100 g. New modalities gained little acceptance among urologist practicing in Saudi Arabia. Hands on workshops may help in educating urologists and introduce these new modalities for the future use.

Subcapsular double-J stent following ureteroscopy: unique complication.

Double-J (DJ) ureteral stent is a standard procedure in daily urological practice performed to relive ureteral obstruction or as a part of other endourological procedures. Although it is a common procedure, the widespread use of ureteral stents has corresponded to the increase in possible complication. We report a unique complication for a patient who presented with a renal subcapsular complete misplacement of DJ stent postureteroscopy for a distal ureteric stone. This challenging complication of ureteral stents is rare and organ threatening.

Changes in pulmonary function tests in breast carcinoma patients treated with locoregional post-mastectomy radiotherapy: results of a pilot study.

BACKGROUND: The aim of present pilot study was to evaluate the changes in pulmonary function tests (PFTs) after locoregional post-mastectomy radiotherapy (PMRT) in breast cancer patients. MATERIALS AND METHODS: Twenty consecutive patients with histopathologically confirmed breast carcinoma stages T1-T4, N1-N2, who were treated with modified radical mastectomy with neoadjuvant or adjuvant chemotherapy underwent PFTs, including forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced expiratory flow at 50%, and peak expiratory flow rate, maximum mid expiratory flow (MMEF25-75), maximal oxygen consumption (VO2max), and carbon monoxide diffusing capacity (DLCO) before, at 30 days, and at 90 days after locoregional PMRT. A two-tailed paired Student's t-test was used to compare mean values among the variables between the groups. RESULTS: A significant drop in FVC, FEV1, and DLCO was noticed at day 90 after the completion of locoregional PMRT with P-values 0.033, 0.042, and 0.031, respectively, while MMEF25-75 and VO2max were not significantly affected (P-values 0.075 and 0.062, respectively) favoring a restrictive lung injury pattern. However, no patient was found to be symptomatic. CONCLUSION: A significant drop in reduction in PFTs occurred at day 90 after the completion of locoregional PMRT. PFTs shall be performed in all breast cancer patients receiving locoregional PMRT for early detection of radiation-induced lung toxicity as all patients in our cohort were found asymptomatic.

Are Health-Related Tweets Evidence Based? Review and Analysis of Health-Related Tweets on Twitter.

BACKGROUND: Health care professionals are utilizing Twitter to communicate, develop disease surveillance systems, and mine health-related information. The immediate users of this health information is the general public, including patients. This necessitates the validation of health-related tweets by health care professionals to ensure they are evidence based and to avoid the use of noncredible information as a basis for critical decisions. OBJECTIVE: The aim of this study was to evaluate health-related tweets on Twitter for validity (evidence based) and to create awareness in the community regarding the importance of evidence-based health-related tweets. METHODS: All tweets containing health-related information in the Arabic language posted April 1-5, 2015, were mined from Twitter. The tweets were classified based on popularity, activity, interaction, and frequency to obtain 25 Twitter accounts (8 physician accounts, 10 nonofficial health institute accounts, 4 dietitian accounts, and 3 government institute accounts) and 625 tweets. These tweets were evaluated by 3 American Board-certified medical consultants and a score was generated (true/false) and interobserver agreement was calculated. RESULTS: A total of 625 health-related Arabic-language tweets were identified from 8 physician accounts, 10 nonofficial health institute accounts, 4 dietician accounts, and 3 government institute accounts. The reviewers labeled 320 (51.2%) tweets as false and 305 (48.8%) tweets as true. Comparative analysis of tweets by account type showed 60 of 75 (80%) tweets by government institutes, 124 of 201 (61.7%) tweets by physicians, and 42 of 101 (41.6%) tweets by dieticians were true. The interobserver agreement was moderate (range 0.78-0.22). More than half of the health-related tweets (169/248, 68.1%) from nonofficial health institutes and dietician accounts (59/101, 58.4%) were false. Tweets by the physicians were more likely to be rated "true" compared to other groups (P<.001). CONCLUSIONS: Approximately half of the medical tweets from professional accounts on Twitter were found to be false based on expert review. Furthermore, most of the evidence-based health-related tweets are posted by government institutes and physicians.
