RESUMO
PURPOSE: Prostate cancer (PCA) is the second most common malignancy in Western countries. Long non-coding RNAs are new markers in disease diagnosis. Our aim of this study was to investigate liquid biopsy biomarkers with high specificity and sensitivity for early diagnosis of PCA patients in Iran. MATERIALS AND METHODS: Blood specimens were collected from 29 PCA, 32 benign prostate hyperplasia (BPH), and 29 control (CTRL) individuals. Real-time PCR analyzed expression amounts of PSA, ARLNC1, UCA1, and PCA3. The ROC curve (receiver operating characteristic curve) analysis evaluated the diagnostic power of the examined molecules for PCA. RESULTS: There was a significant upregulation of PCA3 in PCA and BPH groups compared to the controls (p values for PCA3=< 0.001 and BPH vs. CTRL = 0.0015) while there was no significant difference between PCA and BPH individuals. A significant upregulation of ARLNC1 was seen in BPH group compared to the controls (p value=0.0042). Also, PCA3 expression level showed a significant relationship with prostate volume. There was no significant difference in UCA1 and PSA expression levels among the three groups (>0.05). The PCA3/PSA ratio was significantly increased in PCA and BPH individuals vs. the CTRL group with high sensitivity and specificity. The gene expression of PCA3 and ARLNC1 in the BPH group showed a significant relationship with age. CONCLUSION: Our findings showed that in the diagnosis of prostate cancer, measuring the expression of PCA3, PSA, and ARLNC1 genes is necessary to determine the health, benign, or cancerous status of patients' prostate. Also, selecting the PCA3/PSA ratio provides a new approach for diagnosing this cancer if confirmed in a larger clinical sample size and functional studies.
RESUMO
Mixed epithelial and stromal tumor (MEST) of the kidney is not a common diagnosis. This tumor usually mimics solid-cystic malignant renal tumors and most cases are treated surgically. Here, we presented a 35-year-old female with simultaneous two separate large solid-cystic masses with contrast enhancement in lower and upper pole of left kidney which were managed surgically via partial nephrectomy. Microscopic evaluation showed solid-cystic tumor with variably sized cysts lined by flattened to cuboidal epithelium that was compatible with MEST. Follow up evaluation revealed normal parenchymal renal tissue and proper function without any evidence of local recurrence.
RESUMO
Transplant renal artery stenosis is the most common vascular complication that occurs following kidney transplantation and can lead to graft dysfunction and even its loss. The present report describes A patient with endstage renal disease who underwent living related renal transplantation. He had oliguria and creatinine rise in the post-operative course but all doppler ultrasonography (DUS) during the 2 months post-operation for the renal graft showed a normal mean resistive index in the graft renal artery. Hemodialysis treatment started and continued for 4.5 months. On post-operative day 137, because of the patient's anuria and resistant hypertension, another DUS carried out and reported evidence that suggested arterial stenosis. A computed tomographic (CT) renal angiogram showed a small filling defect in the proximal graft artery that was highly suggestive for transplant renal artery stenosis (TRAS). Following angiography revealed a short linear stenosis. Endovascular intervention and stent placement were performed successfully for the patient on post-operative day 139. This case was initially diagnosed as ongoing acute rejection for which he received antirejection therapy without any significant improvement. After percutaneous transluminal angioplasty (PTA), serum creatinine trended down and urine output improved within 12 h, and they were stable at one-year follow up with a good renal function. It was noteworthy that, despite after a 4.5-month delay in diagnosis and maintenance need for dialysis, the patient responded to endovascular treatment and the graft function became normalized. Our case demonstrates that graft can be saved even if renal artery stenosis is diagnosed after several months of dialysis and diagnosis of end stage renal disease post transplantation.

OBJECTIVES: This study aimed to investigate the possible role of different donor and recipient vessel and ureteral anastomoses on survival and functional outcomes in en bloc kidney transplants. MATERIALS AND METHODS: This retrospective cohort included 99 en bloc kidney transplants performed from December 2005 to March 2022. Recipients were grouped based on donor's vessel (distal [n = 84] or proximal [n = 15] abdominal aorta), recipient's vessel (abdominal aorta [n = 3], external [n = 21], internal [n = 50], or common [n = 25] iliac artery), and ureteral anastomosis (separate [n = 32] or common [n = 67]). Patient and graft survival, complication rates, and estimated glomerular filtration rate trends were compared between groups. RESULTS: Pediatric brain dead donors had a mean age and weight of 37 ± 22 months and 14 ± 4 kg, respectively. Donor and recipient vessel and ureteral anastomoses did not affect overall survival (P = .306, .296, and .225), graft survival (P = .720, .172, and .124), and vascular (P = .347, .689, and .264) and urinary (P = .587, .172, and .385) complication rates. Lymphoceles requiring intervention were significantly more prevalent in the recipient external iliac artery group (P = .008) but were independent of donor vessel and ureteral anastomosis (P = .587 and 1.00). Estimated glomerular filtration rate trend was independentofdonor(P=.921) andrecipient vessel(P=.878 and .536). CONCLUSIONS: We found that different arterial and ureteral anastomoses appear to have comparable outcomes in en bloc kidney transplant with the exception of recipient external iliac artery, which may be slightly inferior because of the relatively higher rate of lymphoceles requiring intervention.

This study aimed to evaluate the outcomes of laparoscopic pyelolithotomy, including its efficacy and feasibility in treatment of large renal stones. All patients who underwent laparoscopic pyelolithotomy operations in a referral center were enrolled from 2003 to 2020. The final analysis included 436 patients. The total stone free rate was 88.3% and the stone-free rate for staghorn/multiple stones versus other types of stones was 81% vs. 91% (P = 0.002). Likewise, the total operation duration was 158 ± 50 and the operation duration for staghorn/multiple stones versus other types of stones was 171 ± 51 min vs. 153 ± 49 min (P < 0.001). The operation duration (169 ± 51 vs. 155 ± 58 vs. 155 ± 42 min) and hospitalization (4.5 ± 2.3 vs. 4.0 ± 2.2 vs. 3.6 ± 1.8) decreased with increasing the surgeons' experience over time. The outcomes of laparoscopic pyelolithotomy for children versus adults versus geriatric patients and in patients with normal versus abnormal kidney anatomy did not reveal statistically significant differences. Laparoscopic pyelolithotomy could be employed as an alternative surgical approach for patients with large kidney stones of any age or with kidney abnormalities provided that appropriate expertise is available to carry out the procedure.

Background: A 1985 law in the Islamic Republic of Iran integrated all health-related educational institutions into the Ministry of Health and established the Ministry of Health and Medical Education to set policies. Aims: We aimed to classify the value concept of the policies that prioritized and to develop a conceptual value-based framework, for the Islamic Republic of Iran's healthcare and medical education systems. Methods: We conducted this qualitative study using a critical, thematic content analysis of value-based statements and policy documents on health and the development of medical education published from 2009 to 2019 in the Islamic Republic of Iran. A total of 210 documents were reviewed and 7 were critically analysed. Value concepts were identified and coded. Results: A total of 69 value concepts were classified into 28 subthemes and 5 main themes: mission values, principal values, procedural values, implementation values, and outcome values. We identified the pattern of the fundamental values to present our conceptual framework. Conclusion: This comprehensive value-based framework can help establish a supportive value-based culture among policymakers, identify under- and over-emphasized issues, and enhance the incorporation of fundamental values across the health and medical education system.

OBJECTIVES: Although several studies have explored the connection between corticosteroids and renal transplant surgical complications, these studies have overlooked several factors. In addition, no review of the literature, to our knowledge, has been conducted to evaluate corticosteroid dose and incidence of posttransplant surgical complications in these patients. Thus, our objective was to carry out a systematic investigation ofthe correlationbetween corticosteroids and surgical complications in renaltransplant patients. MATERIALS AND METHODS: A systematic search was conducted on the PubMed and Embase databases from their inception until April 2023. Retrospective and prospective cohort studies were included if they met the association between corticosteroids and surgical complications. The search strategy was performed using MeSH and non-MeSH key words. Terms used in the electronic search included kidney transplant* OR kidney transplant(mesh) AND steroid* OR steroids(mesh) AND complication* OR intraoperative complications(mesh). RESULTS: From 3274 articles, 8 articles were included in the systematic review. Six studies were conducted as retrospective cohorts and 2 studies as prospective cohorts. The mean age of patients included in the studies was 42.1 years. The studies were conducted between 1981 and 2023. Findings suggested that decreasing the postoperative corticosteroid dosage was associated with a lower incidence of various postoperative surgical complications. CONCLUSIONS: We investigated the potential benefits of reducing the dose of corticosteroids following kidney transplant. Findings suggested thatreducing the dose of corticosteroids following kidney transplant might be a viable strategy for minimizing the risk of surgical complications. However, it is essential to note that the optimal dosage and duration of corticosteroid therapy after kidney transplant may vary for each patient and should be carefully determined by the health care provider.

PURPOSE: To investigate the impact of reducing post-operative oral corticosteroid regimen on associated postoperative surgical complication rate, patient and graft survival in kidney transplant patients. MATERIALS AND METHODS: In this retrospective cohort study, we enrolled patients who received a kidney transplant during two periods of distinct corticosteroid protocols. 592 patients in group 1 received prednisone 2 mg/kg (maximum dose 120 mg) on post-operative days (POD) 1, 2 and 3, 1mg/kg for a week, and tapered it to 10 mg by 3 months post-transplant and sustained the daily 10mg from 3 months post-transplant as maintenance therapy. 639 patients in group 2 received prednisone 50 mg on POD 1, 40mg on POD 2, 30mg on POD 3, 20mg on POD 4, 15mg on POD 5 and continued with 10mg daily from POD 6, as maintenance therapy. The two groups were similar in terms of other immunosuppression drug regimens. RESULTS: 75 (12.7%) patients in group 1 and 24 (3.4%) patients in group 2 developed corticosteroid-related postoperative surgical complications (P < .001). Wound infection (P = .035), incisional hernia (P = .003), infectious collection (P = .004), post-op hemorrhage (P = .005) and ureteral fistula (P = .076) occurred with lower frequency in group 2. Patient survival (1-year: 97.3% vs 97.1%, respectively; P = .85, 5-year: 89.9% vs 94.9%, respectively; P = .06) and graft survival (1-year: 94.6% vs 93.3%, respectively; P = .29, 5-year: 81.2% vs 85.1%, respectively; P = .39) were similar in both groups. CONCLUSION: Post-operative corticosteroid dosage decrement through our protocol would lessen the serious associated postoperative surgical complications, without negative impacts on overall patient and graft survival.
RESUMO
To report our experience with unroofing of ipsilateral lower pole kidney cysts in five patients with adult-type polycystic kidneys [ADPKD] when free implantation of kidney allograft interfered with lower pole native kidney cysts. In all of these patients, the native kidneys extended to the ipsilateral pelvis and bilateral ADPKD caused enlargement of the abdomen on gross examination. Unroofing of lower pole kidney cysts was performed during the same session of allograft transplantation. The decision to unroof lower pole cysts of the ipsilateral kidney was made after observing interference of lower pole cysts with free implantation of the allograft. In patient A, bilateral native nephrectomy was performed 6 weeks after kidney transplantation after consultation with the patient, when there was evidence of the good function of the allograft and the recipient was on a low dose of immunosuppressive medications. In other patients, no need for native nephrectomy observed. This experience suggests the possibility that when large ipsilateral kidney cysts interfere with safe implantation of the allograft, there is an option of performing cyst unroofing at the same session and proceeding with allograft implantation. In many patients, there would be no need for native nephrectomy and of deemed necessary, it will be performed later, when there is evidence of the good function of the allograft and the patient is on good kidney function with a low dose of immunosuppressive medications and a less risk profile for the operation. To our best knowledge, there is no prior such report in the literature.

BACKGROUND: To compare the disease course, histopathological features and survival rates of prostate cancer (PCa) between patients aged ⩽ 55 and > 55 year old. MATERIALS AND METHODS: In this retrospective study, we enrolled 644 patients with organ-confide prostate cancer who had undergone radical prostatectomy from 2005 to 2018. Seventy-six (11.8%) patients were under 55 years of age (group 1) and 568 (88.2%) patients were >55 years old (group 2). RESULTS: Pre-operative hypertension was detected in 4 (5.3%) patients of group 1 and 80 (14.1%) patients of groups 2 (p = 0.029). The mean (±SD) prostate volume was higher in group 2 compared with group 1 (34.1(±8.4) ml vs 54.1(±9.9) ml, p < 0.001). Positive surgery margin was observed in 15 (19.7%) and 58 (10.2%) patients in group 1 and 2, respectively (p = 0.020). Co-existence of diabetes mellitus, mean pre-operative PSA, Gleason's score, and permanent pathology and pathologic stage were similar between the two groups. Log-rank test failed to show any statistical difference in terms of biochemical-relapse free survival, local recurrence-free survival, and metastasis-free survival between the two groups (p = 0.316, 0.441, 0.654, respectively). After performing multivariate analysis, positive surgical margin was the only factor that was independently predictive of biochemical relapse (p < 0.001) and local recurrence/metastasis (p < 0.001). CONCLUSION: No difference was observed in terms of histopathologic features, biochemical relapse, and local recurrence/metastasis-free survival rates between patients younger and older than 55 years of age.

OBJECTIVE: In this study, we aimed to compare the frequency of lymphoceles that needed intervention in recipients who received kidneys from living versus deceased donors. MATERIALS AND METHODS: The records of all patients who underwent kidney transplantation at the Labbafinejad Hospital from 2012 to 2021 were retrospectively reviewed to determine the incidence of lymphoceles that needed intervention for management. RESULTS: From March 2012 to April 2021, 1752 patients received kidney transplantation in Labbafinejad Hospital including 975 transplantations from living donors and 777 transplantations from deceased donors. Symptomatic lymphoceles were observed postoperatively in 23 patients. Symptoms included compressive effect on the ureter, hydroureteronephrosis of the transplanted kidney, frequency, urinary retention, infection, abdominal discomfort, or rise in serum creatinine. Out of 23 patients who needed intervention for symptomatic lymphocele, 15 patients were recipients of living donors and 8 patients were recipients of deceased donors [1.53% versus 1.03%, P=.40]. Intervention consisted of open surgical drainage in 6 patients [4 recipients of living donors and 2 recipients of deceased donors], and nephrostomy insertion in 17 patients. Open operation was necessary in 5 (47%) patients in whom arterial anastomosis was made to the internal iliac artery versus 1 (9%) patient in whom the anastomosis was not made to the internal iliac artery (P=0.15). CONCLUSION: Symptomatic lymphoceles which needed intervention were observed in low frequency (1.31%). Most cases can be managed by endoscopic drainage without relapse. Type of donation had no relationship with the need for open or endoscopic intervention in lymphoceles. A higher proportion of open surgeries to control lymphocele were observed in recipients in whom the internal iliac artery was used for arterial anastomosis however the difference was not statistically significant.

PURPOSE: To evaluate oncological outcomes in patient with positive surgical margin (PSM) following partial nephrectomy (PN). MATERIAL AND METHODS: In this retrospective study, we enrolled the data of patients who underwent PN between 2008 and 2017. The inclusion criteria were a definite diagnosis of kidney tumor who underwent PN with at least one year follow up. RESULTS: From the 450 patients who underwent PN, The PSM was found in 35 (22 male/13 female) patients. 18/237 (7.6%) and 17/213 (7.9%) of them were in open and laparoscopic group, respectively. Clear cell RCC was the most prevalent pathology (18 patients) in the PSM patients. The mean time of follow up was 46 ± 2.02 months. Recurrence was developed in 5 (14.2%) patients. There was no correlation between recurrence and sex (p=1.00), surgery type (p = 0.658), age (p = 0.869), tumor size (p = 0.069), pathology (p = 0.258) and stage (p = 0.744) in PSM patients. Recurrence free survival was similar between the open and laparoscopy groups in PSM patients (p = 0.619). CONCLUSION: Beside numerous advantages of minimally invasive techniques, laparoscopic approach would be comparable to conventional open partial nephrectomy in terms of oncologic outcomes. The rate of recurrence following partial nephrectomy in PSM patients is considerable and closely monitoring is mandatory.

Renal mesenchymal tumors are described as neoplasms with vascular, fibrous, and adipose tissues. The renal lipoma is an extremely rare renal mesenchymal tumor, typically originating from renal capsule and it is usually presented as well circumscribed homogenous fat containing mass. Angiomyolipoma (AML) is the most common benign mesenchymal renal tumor which is composed of mature epithelioid cells. The renal AML usually presented as exophytic, non-infiltrative, and fat contain tumor. The well differentiated renal retroperitoneal liposarcoma and lipoma seem to be misdiagnosed by exophytic renal angiomyolipoma but the renal AML usually arises from renal parenchyma with characteristic images. A 37-year-old woman came to our clinic with rapid growth renal mass and pain. The spiral abdominopelvic computed tomography scan (CT-scan) showed well-circumscribed hypoheterodense fat-containing mass near to middle pole of the right kidney with minimal fat stranding without neovascularity and cortical defect. The Patient underwent off-clamping laparoscopic resection of renal mass with pre-operative impression: liposarcoma versus lipoma of the kidney. The cross-section of the surgical specimen revealed irregular lobulated fatty tissue with hemorrhagic streaks. Definite diagnosis was made by immunohistochemistry study. Spindle cells and epithelioid cells are diffusely and strongly positive for α-smooth muscle actin. The perivascular cells and epithelioid cells are positive for HMB-45 and Melanin. The immunostaining pattern was compatible with angiomyolipoma that originated from renal capsule. In our experience, a rapid growing mass that is accompanied by pain draws the attention to malignant process. The renal AML rarely arises from renal capsule without characteristic images so having high doubt may lead to proper pre-operative diagnosis.

PURPOSE: Data registries are organized systems that facilitate collection, storage, and analysis of data related to a specific disease in a defined population. Here we introduce a data registry system which was designed to cover the four most common urologic cancers (prostate, bladder, renal and testis). MATERIALS AND METHODS: All contributing centers can enter data into the system after logging in with their unique usernames and passwords. In this system, the information of each individual patient will be entered in several structured forms covering various steps of management of the patients. RESULTS: Our proposed registry is an interactive, web-based database designed to collect complete data of patients with common urological cancers. We devised a council that functions as the central committee that will initiate, supervise, and monitor all steps of the projects including data collection, data audit, as well as data analysis and publication. To facilitate manuscript publication, the system will provide assistance and support throughout all the steps of statistical analysis and manuscript preparation. CONCLUSION: This proposed registry can have a national target and is designed to provide evidence-based information that could support strategic planning and national multi-centric studies.

Request for kidney transplantation (K.T.) is increasing rapidly because of the worldwide pandemic of end-stage renal disease, and the most critical issue is organ shortage. The available deceased donors will not resolve the continuing scarcity of organs. It is now professionally and ethically acknowledged and is vital to pay money to the donors for excluding disincentives of living organ donation. Living organ donation should be a vital part of the K.T. Program of any country.

BACKGROUND: To study the current trends in Obstetrics-Gynecology (Ob-Gyn) education and workforce in Iran since 1979 and to discuss the consequences and implications. METHODS: This descriptive-analytical study was conducted to describe the Ob-Gyn residency and fellowship growth and workforce profile in Iran (1979-2017).The first-hand data gathered from MOHME and Iran's Medical Council. The Obstetrician-Gynecologist (Ob-Gyns) per 100000 populations' ratio and the percentage changes calculated and the trends analyzed. RESULTS: Between 1979 and 2017, the proportion of trained Ob-Gyns at national universities increased by 86.27%, the number of certified Ob-Gyns increased by 333% and, female Ob-Gyns increased by 1142%.The ratio of active gynecologists per 100,000 people was 5.0 in 1979 and 8.05 in 2017, represents an increase of 70%. Since 1979 the number of active gynecologists has increased by 278 and the number of active female gynecologists has increased by 996%. Since 1990 the maternal mortality per 100,000 live births decreased by 79.9% in Iran. However, since 1980 the Cesarean proportion increased by 203% in Iran. CONCLUSION: Ob-Gyn education has undergone remarkable growth. Ongoing research should focus on Ob-Gyn's geographic distribution, and potential implications of female Ob-Gyns practice pattern and technologies on women's health.

RESUMO
OBJECTIVES: To evaluate the safety and efficacy of transperitoneal laparoscopic pyelolithotomy in renal stone cases with previous renal surgeries. PATIENTS AND METHODS: In this prospective study, 190 consecutive patients with renal stones, who were candidates for transperitoneal laparoscopic pyelolithotomy, were enrolled. The patients were divided into two groups. In group A, 163 patients without a history of renal surgery underwent standard laparoscopic pyelolithotomy, whereas in group B laparoscopic pyelolithotomy was performed in 27 patients with a history of kidney stone surgery including percutaneous nephrolithotomy or open stone surgery. All intraoperative data including the operating time and complications such as bleeding requiring transfusion were recorded. Postoperative data such as length of hospitalization, hemoglobin level alteration, and other complications were also recorded. RESULTS: There was no significant difference in the preoperative data such as stone size, stone site, age, sex, and stone side between the two groups. There was no significant difference in the stone-free rate between the two groups (p = 0.4). There was no significant difference between the two study groups regarding the operating time, hospital stay, stone-free rate, complications, and transfusion rate. CONCLUSION: Laparoscopic pyelolithotomy can be used as a safe and feasible treatment modality in the setting of previous renal surgery. The complications and stone-free rate of laparoscopic pyelolithotomy in patients with history of renal surgery are acceptable.

OBJECTIVES: A lack of donors continues to be a significant problem. Kidney donors with a body mass index ≥ 30 kg/m² are not suitable for laparoscopic donor nephrectomy; however, some studies have suggested that an obese donor could be an appropriate donor with similar surgical outcomes. Here, we report the results of our 10-year experience of laparoscopic donor nephrectomy, examining the effects of body mass index on the surgical results of laparoscopic donor nephrectomy. MATERIALS AND METHODS: We retrospectively reviewed medical records of patients who underwent laparoscopic donor nephrectomy at the Shahid Beheshti University Medical Science, Urology Center (Tehran, Iran) from 2005 to 2015. The collected information included pretransplant and posttransplant serum levels of hemoglobin and creatinine. We also collected data on surgical outcomes (operation time, cold and warm ischemia, need for blood transfusion, and conversion to open surgery, length of hospital stay, and complication rates) with respect to body mass index categories (≤ 24.9, 25-29.9, and ≥ 30 kg/m²). RESULTS: Of 1083 kidney donors, 732 donors had body mass index of ≤ 24.9 kg/m², 256 had body mass index between 25 and 29.9 kg/m², and 95 had body mass index of ≥ 30 kg/m². Differences among groups were not significant in terms of operation time (P = .558), warm or cold ischemic time (P = .829 and .951, respectively), blood transfusion (P = .873), and length of hospital stay (P = .850). CONCLUSIONS: The laparoscopic approach for donor nephrectomy is a safe and effective method in obese donors without significant postoperative complications.
