Penile carcinoma: A retrospective analysis of 93 patients at a tertiary care center in Jakarta, Indonesia.

OBJECTIVES: Penile carcinoma (PC) is a rare disease with considerable physical and psychological impact. To date, there is no data regarding PC prevalence and characteristics in Indonesia. This study aimed to analyze the characteristics of patients with PC in Indonesia and determine cumulative survival rates and time to disease progression. METHODS: This was a retrospective study of all patients diagnosed with PC at Cipto Mangunkusumo General Hospital from 1995 to 2014, with a minimum of 1 year follow-up. The outcomes of the study were cumulative survival rates and time-to-disease progression. RESULTS: Ninety-three subjects were recruited, with a mean age of 49.44 ± 13.62. Inguinal lymph node dissection (ILND) was performed in 49 (53%) patients. The mean survival in the ILND group was better compared to the non-ILND group (80.7 months vs. 67.1 months; p = 0.032). Time-to-progression in the ILND group was significantly longer than in the non-ILND group (71.7 months vs. 54.3 months; p = 0.022). No significant difference in survival between the total and partial penectomy (PP) groups was observed (p = 0.701). Time-to-progression in total penectomy (TP) was significantly longer than in PP (68 months vs. 56.0 months; p = 0.023). In Cox-regression analysis, after adjustment of other variables, history of ILND, higher stage of cancer, and older age were found to affect the survival of patients. CONCLUSION: ILND in PC led to better survival and reduced disease progression. The type of penectomy is only associated with progression but not survival. TP had a longer time to disease progression compared to PP.

CD44 and CD133 protein expression might serve as a prognostic factor for early occurrence castration-resistant prostate cancer.

BACKGROUND: The occurrence of castration-resistant prostate cancer (CRPC) varies in patients with advanced prostate cancer (PCa) undergoing androgen deprivation therapy (ADT). The rate of occurrence of CRPC may be related to the presence of prostate cancer stem cells (CSC). Thus, this study aims to evaluate the presence of CSC markers (CD44 and CD133) in histopathology tissue at the time of diagnosis and their correlation with the occurrence of CRPC in patients with advanced PCa within 2 years of ADT. METHOD: A retrospective case-control study was conducted to evaluate the incidence of CRPC within 2 years. The inclusion criteria were patients with PCa who had received treatment with ADT and a first-generation anti-androgen (AA) for 2 years. We classified patients based on whether they developed CRPC within 2 years (CRPC) of the therapy or did not experience CRPC within 2 years (non-CRPC) of the therapy. We performed immunohistochemical (IHC) staining for CD44 and CD133 on the prostate biopsy tissue samples. RESULTS: Data were collected from records spanning 2011-2019. We analyzed a total of 65 samples, including 22 patients with CRPC and 43 patients with non-CRPC who had received treatment with LHRH agonists and AA for up to 2 years. Our findings showed a significant H-score difference in CD44 protein expression between CRPC prostate adenocarcinoma samples 869 (200-1329) and non-CRPC 524 (154-1166) (p = 0.033). There was no significant difference in CD133 protein expression between the two groups (p = 0.554). However, there was a significant difference in the nonoccurrence of CRPC between the high expressions of both CD44 and CD133 groups with other expressions of CD44/CD133 groups (25% vs. 75%; p = 0.011; odds ratio = 4.29; 95% confidence interval [1.34, 13.76]). CONCLUSION: This study found a low expression of at least one CD44/CD133 protein in the patients without early occurrence of CRPC. This result might suggest that CD44/CD133 may function as a potential prognostic marker for PCa, especially in a low expression, to identify patients who have a better prognosis regarding the occurrence of early CRPC.

The expression of stem cells markers and its effects on the propensity for recurrence and metastasis in bladder cancer: A systematic review.

Bladder cancer is one of the most frequent cancers of the urinary tract, associated with high recurrence rates and metastasis. Cancer stem cells (CSCs) are a subpopulation of cancer cells characterized by high self-renewal and differentiation capacities, resulting in increased cancer recurrence, larger tumor size, higher rates of metastasis, higher resistance to treatment, and overall poorer prognosis. This study aimed to evaluate the role of CSCs as a prognostic tool to predict the risks of metastasis and recurrence in bladder cancer. A literature search was conducted across seven databases from January 2000 to February 2022 for clinical studies investigating the use of CSCs to determine the prognosis of bladder cancer. The following keywords were used: ("Bladder Cancer" OR "Transitional Cell Carcinoma" OR "Urothelial Carcinoma") AND ("Stem Cell" OR "Stem Gene") AND ("Metastasis" OR "Recurrence"). A total of 12 studies were deemed eligible for inclusion. SOX2, IGF1R, SOX4, ALDH1, CD44, Cripto-1, OCT4, ARRB1, ARRB2, p-TFCP2L1, CDK1, DCLK1, and NANOG, which were all identified as CSC markers. Several of these markers have been implicated in the recurrence and metastasis of tumor in bladder cancer, which played a role as prognostic factor of bladder cancer. Given the pluripotent and highly proliferative properties of CSCs. CSCs may play a role in the complex biological behavior of bladder cancer, including, but not limited to, its high rates of recurrence, metastasis, and resistance to treatment. The detection of cancer stem cell markers offers a promising approach in determining the prognosis of bladder cancer. Further studies in this area are thus warranted and may contribute significantly to the overall management of bladder cancer.

Effect of primary balloon angioplasty on draining vein diameter and volume flow in patients with arteriovenous fistula: A cohort study.

Background: Chronic kidney disease (CKD) and end-stage kidney disease (ESKD) cause major morbidity and mortality in 10% of the global population with CKD. The most common renal replacement therapy is hemodialysis with arteriovenous fistula (AVF) access. AVF often undergoes maturation failure due to feeding artery and draining vein inadequacy. Mechanical dilatation, such as primary balloon angioplasty (PBA), can overcome AVF maturation failure. The volume flow (VF) and diameter of the draining veins in AVF patients must be known to evaluate the effect of PBA on AVF maturation. This study aims to analyze the impact of PBA on VF and draining vein diameter in ESKD patients undergoing AVF surgery. Methods: A retrospective cohort clinical trial was conducted at our institution. A total of 75 participants had AVF with an arterial diameter >1.5 mm or vein diameter at the AVF creation site of 2-4 mm. The subjects were divided into 2 groups: the intervention group undergoing PBA (n = 36) and the control group, without PBA (n = 39). PBA was performed using a Mustang ballon (3-6 mm, Medtronic). Follow-ups were conducted at 1 week, 2 weeks, and 6 weeks after AVF creation. Results: Based on the data, the diameter and VF of the draining veins were significantly larger in the intervention group than in the control group (p < 0.001). Furthermore, we found significant differences in the mean diameter and VF of the draining veins between the control and intervention groups at all stages of examination, from preoperatively to 6 weeks postoperatively (p < 0.001). The strength of the analysis was more than 80%. Conclusion: PBA can increase the diameter and VF of the draining veins in patients with AVF.

Retroperitoneoscopic proximal ureter resection and ureteroureterostomy as an alternative management for upper tract urothelial carcinoma: A case report.

Radical nephroureterectomy (RNU) with bladder cuff removal is the treatment of choice for upper tract urothelial carcinoma (UTUC). Partial ureterectomy (PU) with ureteroureterostomy in this case has shown a good result. We herein report an elderly woman with adenocarcinoma colon complaining gross intermittent hematuria and solid ureteral mass on NCCT. Patient declined RNU, so we performed PU with ureteroureterostomy. Histology examination showed high-grade infiltrating urothelial carcinoma with negative margin. Four cycles of Gemcitabine and cisplatin were given. Routine follow up and evaluation were done without any mass progression. PU and ureteroureterostomy with adjuvant chemotherapy are an alternative procedure for UTUC.

Adenocarcinoma mucinosum of extrophy bladder: A rare case report.

INTRODUCTION: Bladder exstrophy is a rare congenital anomaly while, bladder adenocarcinoma mucinous type is a rare type of bladder cancer, with aggressive behavior and inadequate response to radiation and chemotherapy. In extremely rare cases, untreated bladder exstrophy could transform into bladder mucinous adenocarcinoma. CASE PRESENTATION: We report a case of a 41-year-old male with untreated bladder exstrophy that transformed into mucinous adenocarcinoma. The patient also had epispadias and a right inguinal hernia. Joint procedures were conducted to perform radical cystectomy, total penectomy and W-Pouch continent urostomy, inguinal hernia repair, osteotomy, and keystone and scrotal flap by split-thickness skin graft (STSG) for wound closure. The patient progressed well after surgery, two months after initial procedure, nephrostomies were conducted due to pouches stenosis. Due to the government's limited transportation and lockdown policy, as the Covid-19 pandemic occurred, the patient could not come to the hospital for routine follow-up and died nine-month after surgery. CLINICAL DISCUSSION: Bladder exstrophy is one of the risk factors of bladder cancer. Transformation of bladder exstrophy into mucinous adenocarcinoma is extremely rare, as the case is the first case to be discovered in Indonesia. Surgery, followed with a strict follow-up regime, is mainstay of treatment in this type of malignancy. CONCLUSION: Adenocarcinoma of mucinous type is a scarce type of bladder exstrophy malignancies. A multidiscipline approach is mandatory in these cases. Strict and regular follow up are suggested for these cases.

Silent Hypertensive Crisis in an Adolescent: First Case Report of Pediatric Pheochromocytoma from Indonesia.

Secondary hypertension in children, to the rare extent, can be caused by endocrine factors such as pheochromocytoma, an adrenal tumor that secretes catecholamine. Only a few cases have been reported in the past 3 decades. To the best of our knowledge, this is the first case report of pediatric pheochromocytoma from Indonesia. We reviewed a case of a 16-year-old Indonesian boy with history of silent hypertensive crisis who was referred from a remote area in an island to the pediatric nephrology clinic at Cipto Mangunkusumo Hospital, Jakarta, Indonesia. Despite medications, his symptoms persisted for 14 months. At the pediatric nephrology clinic, pheochromocytoma was suspected due to symptoms of catecholamine secretion presented, which was palpitation, diaphoresis, and weight loss. However, as the urine catecholamine test was unavailable in Indonesia, the urine sample was sent to a laboratory outside the country. The elevated level of urine metanephrine, focal pathological uptake in the right adrenal mass seen on 131I-MIBG, and histopathology examination confirmed the suspicion of pheochromocytoma. Following the tumor resection, he has been living with normal blood pressure without antihypertensive medications. This case highlights that pheochromocytoma should always be included in the differential diagnoses of any atypical presentation of hypertension. In limited resources setting, high clinical awareness of pheochromocytoma is required to facilitate prompt referral. Suspicion of pheochromocytoma should be followed by measurement of urine metanephrine levels. Early diagnosis of pheochromocytoma would fasten the optimal cure, alleviate the symptoms of catecholamine release, and reverse hypertension.

The Role of 3D-Printed Phantoms and Devices for Organ-specified Appliances in Urology.

Urology is one of the fields that are always at the frontline of bringing scientific advancements into clinical practice, including 3D printing (3DP). This study aims to discuss and presents the current role of 3D-printed phantoms and devices for organ-specified applications in urology. The discussion started with a literature search regarding the two mentioned topics within PubMed, Embase, Scopus, and EBSCOhost databases. 3D-printed urological organ phantoms are reported for providing residents new insight regarding anatomical characteristics of organs, either normal or diseased, in a tangible manner. Furthermore, 3D-printed organ phantoms also helped urologists to prepare a pre-surgical planning strategy with detailed anatomical models of the diseased organs. In some centers, 3DP technology also contributed to developing specified devices for disease management. To date, urologists have been benefitted by 3D-printed phantoms and devices in the education and disease management of organs of in the genitourinary system, including kidney, bladder, prostate, ureter, urethra, penis, and adrenal. It is safe to say that 3DP technology can bring remarkable changes to daily urological practices.

Meta-analysis of neoadjuvant chemotherapy compared to radical cystectomy alone in improving overall survival of muscle-invasive bladder cancer patients.

BACKGROUND: Most patients with muscle-invasive bladder cancer (MIBC) developed metastasis within 2 years, even after radical cystectomy (RC). The recurrence rate of MIBC was more than 50% of the cases. A meta-analysis conducted by Yin et al. showed that neoadjuvant chemotherapy (NAC) + RC improves overall survival in MIBC compared with RC only. However, a new meta-analysis by Li et al. concluded that NAC + RC was not superior to RC only in improving overall survival. The inconsistencies of these studies required further comprehensive analysis to recommend NAC use in bladder cancer treatment. Therefore, this meta-analysis aims to analyze previous studies that compare the efficacy of NAC + RC versus RC only to improve overall survival of MIBC. METHODS: The articles were searched using Pubmed with keywords "muscle-invasive bladder cancer", "neoadjuvant chemotherapy", "cystectomy", and "overall survival". The articles that were published until June 2020 were screened. The overall survival outcome was analyzed as hazard ratio (HR) and presented in a forest plot. RESULT: Seventeen studies were included in meta-analysis with a total sample of 13,391 patients, consist of 2890 received NAC followed by RC and 10,418 underwent RC only. Two studies used methotrexate/vinblastine/doxorubicin/cisplatin (MVAC), two studies used gemcitabine/cisplatin (GC), one study used Cisplatin-based regimen, one study used MVAC or GC, one study used gemcitabine/carboplatin (GCarbo) or GC or MVAC, one study used Cisplatin/Gemcitabine or MVAC, one study used Cisplatin only, one study used Cisplatin-based (GC, MVAC) or non-Cisplatin-based (combined paclitaxel/gemcitabine/carboplatin), one study used GC, MVAC, Carboplatin, or Gemcitabine/Nedaplatin (GN), and five studies did not mention the regimen The overall survival in the NAC + RC only group was significantly better than the RC only group (HR 0.82 [0.71-0.95], p = 0.009). CONCLUSION: NAC + RC is recommended to improve overall survival in MIBC patients. A further study assessing side effects and quality of life regarding NAC + RC is needed to establish a strong recommendation regarding this therapy.

Cross-continental comparison of safety and protection measures amongst urologists during COVID-19.

OBJECTIVES: To determine the well-being of urologists worldwide during the coronavirus disease 2019 pandemic, and whether they have adequate personal protective equipment knowledge and supplies appropriate to their clinical setting. METHODS: Urologists worldwide completed a Société Internationale d'Urologie online survey from 16 April 2020 until 1 May 2020. Analysis was carried out to evaluate their knowledge about protecting themselves and others in the workplace, including their confidence in their ability to remain safe at work, and any regional differences. RESULTS: There were 3488 respondents from 109 countries. Urologists who stated they were moderately comfortable that their work environment offers good protection against coronavirus disease 2019 showed a total mean satisfaction level of 5.99 (on a "0 = not at all" to "10 = very" scale). A large majority (86.33%) were confident about protecting themselves from coronavirus disease 2019 at work. However, only about one-third reported their institution provided the required personal protective equipment (35.78%), and nearly half indicated their hospital has or had limited personal protective equipment availability (48.08%). Worldwide, a large majority of respondents answered affirmatively for testing the healthcare team (83.09%). Approximately half of the respondents (52.85%) across all regions indicated that all surgical team members face an equal risk of contracting coronavirus disease 2019 (52.85%). Nearly one-third of respondents reported that they had experienced social avoidance (28.97%). CONCLUSIONS: Our results show that urologists lack up-to-date knowledge of preferred protocols for personal protective equipment selection and use, social distancing, and coronavirus disease 2019 testing. These data can provide insights into functional domains from which other specialties could also benefit.

Effects of low versus standard pressure pneumoperitoneum on renal syndecan-1 shedding and VEGF receptor-2 expression in living-donor nephrectomy: a randomized controlled study.

BACKGROUND: Laparoscopic nephrectomy is a preferred technique for living kidney donation. However, positive-pressure pneumoperitoneum may have an unfavorable effect on the remaining kidney and other distant organs due to inflamed vascular endothelium and renal tubular cell injury in response to increased systemic inflammation. Early detection of vascular endothelial and renal tubular response is needed to prevent further kidney injury due to increased intraabdominal pressure induced by pneumoperitoneum. Transperitoneal laparoscopic living donor nephrectomy represented a human model of mild increasing intraabdominal pressure. This study aimed to assess the effect of increased intraabdominal pressure on vascular endothelium and renal tubular cells by comparing the effects of low and standard pressure pneumoperitoneum on vascular endothelial growth factor receptor-2 (VEGFR-2) expression and the shedding of syndecan-1 as the early markers to a systemic inflammation. METHODS: We conducted a prospective randomized study on 44 patients undergoing laparoscopic donor nephrectomy. Subjects were assigned to standard (12 mmHg) or low pressure (8 mmHg) groups. Baseline, intraoperative, and postoperative plasma interleukin-6, syndecan-1, and sVEGFR-2 were quantified by ELISA. Syndecan-1 and VEGFR-2 expression were assessed immunohistochemically in renal cortex tissue. Renal tubule and peritubular capillary ultrastructures were examined using electron microscopy. Perioperative hemodynamic changes, end-tidal CO2, serum creatinine, blood urea nitrogen, and urinary KIM-1 were recorded. RESULTS: The low pressure group showed lower intra- and postoperative heart rate, intraoperative plasma IL-6, sVEGFR-2 levels and plasma syndecan-1 than standard pressure group. Proximal tubule syndecan-1 expression was higher in the low pressure group. Proximal-distal tubules and peritubular capillary endothelium VEGFR-2 expression were lower in low pressure group. The low pressure group showed renal tubule and peritubular capillary ultrastructure with intact cell membranes, clear cell boundaries, and intact brush borders, while standard pressure group showed swollen nuclei, tenuous cell membrane, distant boundaries, vacuolizations, and detached brush borders. CONCLUSION: The low pressure pneumoperitoneum attenuated the inflammatory response and resulted in reduction of syndecan-1 shedding and VEGFR-2 expression as the renal tubular and vascular endothelial proinflammatory markers to injury due to a systemic inflammation in laparoscopic nephrectomy.

TUR-P phantom for resident surgical training: food-based design as a human mimicking model of the prostate.

PURPOSE: This study would like to develop a novel model similar to human prostate in terms of its texture profile, sensation upon resection, and anatomical hallmarks for resident transurethral resection of the prostate (TUR-P) training. METHODS: Ten phantom designs were proposed, using broadly available ingredients and a homemade protocol. Three steps of evaluation and development were done: objective measurement measuring texture profile (e.g. hardness, elasticity, cohesiveness/consistency, and adhesiveness/stickiness) using TA-XT2i Texture Analyzer (Llyod Instruments, Ametek Inc) to compare the designs with human prostate, finding the most similar design to prostate; expert consensus by a panel of urologist/senior residents comparing the simulation of TUR-P on the selected design with pre-existing control phantom; and anatomical design development using 3D printing for molding. RESULTS: Texture profile analysis for mean hardness, elasticity, cohesiveness/consistency, and adhesiveness/stickiness of human prostate was 3753.4 ± 673.4, 85 ± 1.9, 0.7 ± 0.03, and 0, respectively, and design IX was the most similar to human prostate (3660.7 ± 465.6, 87.0 ± 2.5, 0.6 ± 0.05, 0). Furthermore, expert consensus showed superiority of design IX compared with pre-existing control phantom (16.95 ± 1.36 vs 8.86 ± 3.10; P < 0.001). Most of the respondents agreed that the texture, consistency, and phantom ability to mimic human prostate upon resection were similar with human prostate, though hallmarks of the prostate e.g. veromontanum, and lobes were lacking. We used these feedbacks to develop a mold, designed to produce these important anatomical hallmarks. CONCLUSION: This study developed a cost-effective prostate model from a food-based design that is similar to human prostate in terms of its texture and sensation upon TUR-P resection provided with important anatomical hallmarks.

A randomized controlled trial on analgesic effect of repeated Quadratus Lumborum block versus continuous epidural analgesia following laparoscopic nephrectomy.

BACKGROUND: Epidural analgesia as the effective pain management for abdominal surgery has side effects such as paresthesia, hypotension, hematomas, and impaired motoric of lower limbs. The quadratus lumborum block (QLB) has potential as an abdominal truncal block, however, its analgesic efficacy has never been compared to epidural analgesia on laparoscopic nephrectomy. This prospective randomized controlled study compared the effectiveness of QLB with the epidural analgesia technique in relieving postoperative pain following transperitoneal laparoscopic nephrectomy. METHODS: Sixty-two patients underwent laparoscopic donor nephrectomy and were randomized to receive QLB (n = 31) or continuous epidural (n = 31). The QLB group received bilateral QLB using 0.25% bupivacaine and the epidural group received 6 ml/h of 0.25% bupivacaine for intraoperative analgesia. As postoperative analgesia, the QLB group received repeated bilateral QLB with the same dose and the epidural group received 6 ml/h of 0.125% bupivacaine for 24 h after surgery completion. The primary outcome was the 24-h cumulative morphine requirement after surgery. The secondary outcome was the postoperative pain scores. Sensory block coverage, hemodynamic changes, Bromage score, postoperative nausea-vomiting (PONV), paresthesia, and duration of urinary catheter usage were recorded and analyzed. RESULT: The 24-h cumulative morphine requirement and pain scores after surgery were comparable between the QLB and epidural groups. The coverage of QLB was extended from T9 to L2 and the continuous epidural block was extended from T8 to L3 dermatomes. The mean arterial pressure (MAP) measured at 24 h after surgery was lower in the epidural group (p = 0.001). Bromage score, incidence of PONV, and paresthesia were not significantly different between the two groups. Duration of urinary catheter usage was shorter (p < 0.001) in the QLB group. CONCLUSION: The repeated QLB had a similar 24-h cumulative morphine requirement, comparable postoperative pain scores and sensory blockade, higher postoperative MAP, a similar degree of motoric block, no difference in the incidence of PONV and paresthesia, and shorter urinary catheter usage, compared to the continuous epidural analgesia following transperitoneal laparoscopic nephrectomy. TRIAL REGISTRATION: ClinicalTrial.gov NCT03520205 retrospectively registered on May 9th 2018.

Adherence of Indonesian urologists to practice guidelines for the management of benign prostatic hyperplasia.

BACKGROUND: Clinical guideline is built to provide consistent, efficient, and high quality of medical care based on recent evidence. This study aimed to investigate the adherence of Indonesian urologists to clinical guidelines for the management of benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: This was a cross-sectional study using questionnaire conducted between January and June 2017. Respondents were Indonesian urologists registered as members of Indonesia Urological Association and had already practice in urology for at least 6 months. Questionnaires were sent via e-mail and Google Form. The level of adherence was measured using scoring system decided by authors' agreement. All data were processed using SPSS, version 23, and presented in descriptive fashion. RESULTS: Of 352 urologists who fulfilled inclusion and exclusion criteria, 209 (59.4%) respondents returned the questionnaire. Most of respondents (95.2%) used Indonesia Urological Association BPH guidelines as their clinical practice guidance. Routinely performed recommended examination, such as symptom scoring system, digital rectal examination, urinalysis, uroflowmetry, postvoid residual urine, and prostate imaging were used by 89.9%, 92.5%, 70.4%, 50.8%, 53.3%, and 98.6% respondents, respectively. After patient is diagnosed with BPH, most of respondents considered medical therapy (99%), surgical therapy (93%), and watchful waiting (78.4), with alpha-blocker as the drugs most preferred by respondents. For indication to perform surgery for BPH, only bladder stones, decreased renal function, and trial without catheter failure were considered by more than 85% of respondents. Open prostate surgery was performed by 54.8% respondents for the following reasons: large prostate volume, presence of bladder stone, unavailability of endourology equipments, abnormality of bladder, and residency training program. At last, this study found median (minimum-maximum) of Indonesian urologists adherence level toward BPH guidelines is 78.5% (28.6%-100%). CONCLUSIONS: In general, Indonesian urologists have a good adherence toward guidelines. However, there is still wide variation of their adherence to it.

Laparoscopic procurement of single versus multiple artery kidney allografts: Meta-analysis of comparative studies.

Laparoscopic donor nephrectomy has become the standard procedure to procure kidney graft. Transplantation using multiple arteries allograft is technically more challenging and still controversial with respect to renal transplantation outcomes. The objective of this study was to examine the transplantation outcome in both donor and recipient outcome of multiple arteries allograft kidney compared with single renal artery kidney. Eligible studies were identified from electronic databases: PubMed, Cochrane CENTRAL, Science Direct, and CINAHL as of October 2016. Relevant parameters explored using Review Manager V5.2 included donor and recipient outcomes. Twenty-four studies were included in this meta-analysis. Compared with SA, MA kidneys were associated with a longer donor operative time. There was no difference between donor length of stay, intraoperative blood loss, hospital stay, first warm ischemic time (WIT-I), and donor surgical complications in donors with multiple arteries compared with single. There was an increased risk of one-year graft loss (OR 1.57, 95% CI 1.09 to 2.26, p = 0.016), recipient vascular complications and recipient ureteral complications in multiple arteries compared with single artery allografts. Kidney transplantation with multiple arteries is relatively as safe as single artery in terms of donor outcomes. However, transplantation with multiple arteries allograft had several potential negative impacts on the recipient outcomes.

Comparison of Three-Quadrant Transversus Abdominis Plane Block and Continuous Epidural Block for Postoperative Analgesia After Transperitoneal Laparoscopic Nephrectomy.

BACKGROUND: Postoperative pain management is important for the early recovery of the living donor patient. Patient-controlled opioid analgesia, epidural analgesia, or a combination of both is the preferred pain management after abdominal surgery although these approaches have serious side effects. The transversus abdominis plane (TAP) block has been increasingly used for postoperative pain management and the addition of dexamethasone to local anesthetic can prolong the duration of action. OBJECTIVES: This study evaluated the efficacy of ultrasound-guided three-quadrant TAP block analgesia with the addition of dexamethasone, compared to the continuous epidural analgesia in postoperative cumulative opioid consumption and pain scale in the first 24 hours following transperitoneal laparoscopic living donor nephrectomy. METHODS: A prospective randomized control study was conducted on 50 patients with ASA I-II, 18 - 65 years old, BMI 18 - 30, and undergoing transperitoneal laparoscopic donor nephrectomy under general anesthesia. The patients were randomly assigned into either a three-quadrant TAP block group (n = 25) with 20 mL of 0.25% bupivacaine plus dexamethasone 8 mg or a continuous epidural group (n = 25) using 0.125% bupivacaine postoperatively. The morphine consumption and the numerical rating scale (NRS) at rest and movement were evaluated at 2, 6, 12, and 24 hours postoperatively. The postoperative first-time mobilization and duration of urinary catheter usage were recorded. RESULTS: Patients demographic characteristics were similar in the two groups. During 24 hours after the surgery, cumulative morphine consumption (P = 0.232), the NRS at rest and movement (P > 0.05), and the first-time mobilization (P = 0.075) were not significantly different between the groups, except that the NRS during movement at 12 hours was significantly lower in the TAP block group (P = 0.004). The duration of urinary catheterization was significantly longer as a side effect in the continuous epidural group (P < 0.001). CONCLUSIONS: The three-quadrant TAP block with the addition of dexamethasone showed comparable analgesic effects as the continuous epidural analgesia in cumulative opioid consumption and pain scale in the first 24 hours following transperitoneal laparoscopic donor nephrectomy.

Prostate specific antigen (PSA) kinetic as a prognostic factor in metastatic prostate cancer receiving androgen deprivation therapy: systematic review and meta-analysis.

Aim: Metastatic prostate cancer (mPCa) has a poor outcome with median survival of two to five years. The use of androgen deprivation therapy (ADT) is a gold standard in management of this stage.  Aim of this study is to analyze the prognostic value of PSA kinetics of patient treated with hormonal therapy related to survival from several published studies Method: Systematic review and meta-analysis was performed using literature searching in the electronic databases of MEDLINE, Science Direct, and Cochrane Library. Inclusion criteria were mPCa receiving ADT, a study analyzing Progression Free Survival (PFS), Overall Survival (OS), or Cancer Specific Survival (CSS) and prognostic factor of survival related to PSA kinetics (initial PSA, PSA nadir, and time to achieve nadir (TTN)). The exclusion criteria were metastatic castration resistant of prostate cancer (mCRPC) and non-metastatic disease. Generic inverse variance method was used to combine hazard ratio (HR) within the studies. Meta-analysis was performed using Review Manager 5.2 and a p-value <0.05 was considered statistically significant. Results: We found 873 citations throughout database searching with 17 studies were consistent with inclusion criteria. However, just 10 studies were analyzed in the quantitative analysis. Most of the studies had a good methodological quality based on Ottawa Scale. No significant association between initial PSA and PFS. In addition, there was no association between initial PSA and CSS/ OS. We found association of reduced PFS (HR 2.22; 95% CI 1.82 to 2.70) and OS/ CSS (HR 3.31; 95% CI 2.01-5.43) of patient with high PSA nadir. Shorter TTN was correlated with poor result of survival either PFS (HR 2.41; 95% CI 1.19 - 4.86) or CSS/ OS (HR 1.80; 95%CI  1.42 - 2.30) Conclusion: Initial PSA before starting ADT do not associated with survival in mPCa.  There is association of PSA nadir and TTN with survival.

Prostate cancer detection rate in Indonesian men.

PURPOSES OF THE STUDY: To evaluate the overall detection rate of prostate cancer in biopsies according to serum prostate-specific antigen levels, determine the number of cores biopsied in Indonesian men, and provide a correlated staging of prostate cancer patients at varying intervals of prostate-specific antigen levels. METHODS: We retrospectively analyzed the data from Indonesian men who had undergone prostate biopsy at two national referral medical centers in Jakarta from January 1995 to December 2014. Prostate biopsy was performed when levels of prostate-specific antigen were>4.0 ng/mL or malignancy was suspected upon digital rectal examination. RESULTS: Of 2942 men who underwent biopsies, 844 (28.7%) were diagnosed with prostate cancer. When patients were stratified into five subgroups by serum prostate-specific antigen levels (< 4.0, 4.0-9.9, 10.0-19.9, 20.0-100.0, and>100.0 ng/mL), the overall detection rate of prostate cancer was 21.0%, 9.3%, 13.1%, 35.4%, and 92.9%, respectively. The detection rate was significantly higher in patients who underwent 10-core biopsies than in patients who underwent 6-core biopsies (31.6% vs. 22.4%, p<0.001). The receiver operating characteristic analysis to detect locally advanced/metastatic prostate cancer found that serum prostate-specific antigen levels of 42.7 ng/mL had a sensitivity of 74%, specificity of 73%, positive predictive value of 85.2%, and negative predictive value of 57.5%, with area under the curve of 0.81 (95% confidence interal 0.78 to 0.84). CONCLUSION: The overall detection rate of prostate cancer in Indonesian men was 28.7%. The prostate cancer detection rate appeared to be lower than that observed in white men.

Kidney transplantation: A new era of laparoscopic living donor nephrectomy in Indonesia.

BACKGROUND: Since its introduction in 1995, laparoscopic living donor nephrectomy (LLDN) has been a standard procedure in many transplantation centers worldwide. In 2011, LLDN was performed for the first time in Indonesia and became a standard procedure at our institution. The aim of this study is to evaluate the first 250 cases of LLDN at our institution. METHODS: Retrospective analyses were conducted of the first 250 cases of LLDN. All operations were performed between November 2011 and July 2015 at Cipto Mangunkusumo Hospital, Jakarta. We grouped each 100 consecutive cases and the last 50 cases (three groups) to evaluate operation-related parameters, and complications. RESULTS: Significant decreases in the first warm ischemic time, blood loss, length of stay, and number of complications were observed among the three groups. There was only one conversion to open case during LLDN surgery and no mortality case observed. CONCLUSION: Laparoscopic living donor nephrectomies had been performed successfully with improvement of surgical parameter in due time. Thus, laparoscopic approach has entered a new era for kidney procurement in Indonesia.

Obese Kidney Donors in the Laparoscopic Living Nephrectomy Era: How Safe?

BACKGROUND Obesity is a major worldwide health problem, causing up to 3.4 million deaths per year. It is considered to be a relative contraindication for laparoscopic surgery. Laparoscopic living donor nephrectomy is the criterion standard procedure for kidney procurement in many transplant centers. However, the selection of the obese donors undergoing laparoscopic nephrectomies is still debatable. The objective of this study was to compare short-term results of obese donors and non-obese donors undergoing laparoscopic living donor nephrectomies. MATERIAL AND METHODS A retrospective analysis of 259 live donors between November 2011 and August 2015 was performed. Body mass index equal to or more than 30 kg/m2 was categorized as obese. Twenty subjects were categorized as obese donors. We randomly assigned for 30 non-obese donors to the control group. Intra-operative and post-operative data were compared between these 2 groups. A p-value ≤0.05 was considered a significant difference. RESULTS Donor characteristics were the same in the 2 groups. No significant differences were found in the first warm ischemic time, estimated blood loss, or postoperative pain. The operative time in the obese group was significantly longer than in the control group (270 vs. 245 min, p≤0.05). The hospital stay was also significantly longer in the obese group (4 vs. 3 days, p≤0.05). CONCLUSIONS At our hospital, obese donors had short-term results comparable to those of non-obese donors in laparoscopic living nephrectomy. While longer operative time and length of stay were found, there were no significant complications observed. Long-term outcomes should be evaluated to justify use of obese donors.
