PTEN, ERG, SPINK1, and TFF3 Status and Relationship in a Prostate Cancer Cohort from Jordanian Arab Population.

Background and Objectives: Prognostic biomarkers in prostate cancer (PCa) include PTEN, ERG, SPINK1, and TFF3. Their relationships and patterns of expression in PCa in developing countries, including Jordan, have not yet been investigated. Materials and Methods: A tissue microarray (TMA) of PCa patients was taken from paraffin-embedded tissue blocks for 130 patients. PTEN, ERG, SPINK1, and TFF3 expression profiles were examined using immunohistochemistry (IHC) and correlated with each other and other clinicopathological factors. Results: PTEN loss of any degree was observed in 42.9% of PCa cases. ERG and TFF3 were expressed in 59.3% and 46.5% of PCa cases, respectively. SPINK1 expression was observed in 6 out of 104 PCa cases (5.4%). Among all PCa cases (n = 104), 3.8% (n = 4) showed SPINK1+/ERG+ phenotype, 1.9% (n = 2) showed SPINK1+/ERG- phenotype, 56.7% (n = 59) showed SPINK1-/ERG+ phenotype, and 37.5% showed SPINK1-/ERG- phenotype (n = 39). Among ERG positive cases (n = 63), 6.3% were SPINK1 positive. Among SPINK1 positive cases (n = 6), 66.7% were ERG positive. SPINK1 expression was predominantly observed in a subgroup of cancers that expressed TFF3 (6/6). Additionally, a statistically significant loss of PTEN expression was observed from Gleason Score 6 (GS6) (Grade Group 1 (GG1)) to GS9-10 (GG5); (p-value 0.019). Conclusions: This is the first study to look at the status of the PTEN, ERG, SPINK1, and TFF3 genes in a Jordanian Arab population. Loss of PTEN has been linked to more aggressive prostate cancer with high GSs/GGs. SPINK1 expression was predominantly observed in a subgroup of cancers that expressed TFF3. Our results call for screening these biomarkers for grading and molecular subtyping of the disease.

Discovery of a novel genetic variant in the N-acetyltransferase2 (NAT2) gene that is associated with bladder cancer risk.

Smoking is a main risk factor for bladder cancer (BC). NAT2 is a drug-metabolizing enzyme that catalyses the detoxification of many xenobiotics and carcinogens. Single nucleotide polymorphism (SNP) in NAT2 results in different acetylation phenotypes (fast, intermediate or slow). Certain NAT2 SNPs were associated with BC and/or modified the association of BC with smoking. However, limited evidence is available among BC patients or smokers from Jordan. This study aimed to discover novel SNPs in NAT2 and to assess the association with BC. This was a case-control study among 120 BC patients and 120 controls. Amplification of a 446 bp fragment of NAT2 encoding the N-catalytic domain was conducted using a polymerase chain reaction. Gene sequencing was done using Sanger-based technology. A total of 40 SNPs were detected. Two variants were significantly associated with BC (p<0.05); namely a novel c.87G>A and the reported c.341T>C. Regarding c.87G>A, genotype distribution was significantly associated with BC and subgroup analysis confirmed that this was significant in both smokers (p=0.007) and non-smokers (p=0.001). Regression subgroup analysis suggested GA as a risk factor among smokers (AOR= 2.356). The frequencies of TC and CC genotypes of c.341T>C were significantly higher in BC (p<0.05). This was statistically significant among smokers only (p=0.044), upon subgroup analysis. Multivariate analysis showed that subjects with TC genotype are 6.15 more likely to develop BC and regression subgroup analysis revealed TC as a risk factor among smokers (AOR=5.47). This is the first study from Jordan to report the association of smoking and two NAT2 variants with BC. The data supports the use of GA and TC genotypes of the novel c.87G>A and the reported c.341T>C SNPs, respectively as potential biomarkers of BC, particularly among smokers. Future investigations with a larger population are required to support our findings.

Chromophobe renal cell carcinoma with sarcomatoid and heterologous osteosarcoma-like differentiation: a case report and literature review.

Chromophobe renal cell carcinoma (CRCC) is a subtype of renal cell carcinoma (RCC) with a favorable prognosis. Sarcomatoid differentiation in RCC is assumed to be the outcome of the parent tumor's dedifferentiation and associated with poorer prognosis. Sarcomatoid differentiation can be detected in CRCC as well as other subtypes, but the occurrence of divergent osteosarcoma-like components in sarcomatoid CRCC is extremely unusual. Only six cases have been previously reported in the literature, we reviewed them and presented the seventh case in a 71-year-old male who had a left kidney heterogeneous mass. The resected tumor showed a sarcoma-like spindle cell area with an adjacent osteosarcoma area producing lacy bone material and bony trabeculae in a hard area mixed with a typical CRCC. In conclusion, sarcomatoid CRCC with osteosarcomatous differentiation is a very rare tumor and should be kept in mind especially when dealing with small or frozen sections biopsies.

Cutaneous metastasis as the first presentation of poorly differentiated renal cell carcinoma: A case report.

Renal cell carcinoma (RCC) exhibits a propensity for unusual wide metastasis. Cutaneous metastasis from RCC is a rare and poorly recognized clinical entity. We present a case of cutaneous metastasis of poorly differentiated RCC in 49-year-old male patient. In the presented case, the skin lesion was the first sign of widely spread RCC. After the establishment of the diagnosis using radiological and histopathological assessments, the patient was labeled as a terminal case and was referred for pain management. He deceased after 6 months of the initial presentation.

The Prognostic Utility of Lymphocyte-Based Measures and Ratios in Chemotherapy-Induced Febrile Neutropenia Patients following Granulocyte Colony-Stimulating Factor Therapy.

Background and Objectives: Chemotherapy-induced febrile neutropenia is the most widespread oncologic emergency with high morbidity and mortality rates. Herein we present a retrospective risk factor identification study to evaluate the prognostic role of lymphocyte-based measures and ratios in a cohort of chemotherapy-induced febrile neutropenia patients following granulocyte colony-stimulating factor (G-CSF) therapy. Materials and Methods: The electronic medical records at our center were utilized to identify patients with a first attack of chemotherapy-induced febrile neutropenia and were treated accordingly with G-CSF between January 2010 to December 2020. Patients' demographics and disease characteristics along with laboratory tests data were extracted. Prognosis-related indicators were the absolute neutrophil count (ANC) at admission and the following 6 days besides the length of stay and mortality rate. Results: A total of 80 patients were enrolled, which were divided according to the absolute lymphocyte count at admission into two groups, the first includes lymphopenia patients (n = 55) and the other is the non-lymphopenia group (n = 25) with a cutoff point of 700 lymphocytes/µL. Demographics and baseline characteristics were generally insignificant among the two groups but the white blood cell count was higher in the non-lymphopenia group. ANC, neutrophils percentage and ANC difference in reference to admission among the two study groups were totally insignificant. The same insignificant pattern was observed in the length of stay and the mortality rate. Univariate analysis utilizing the ANC difference compared to the admission day as the dependent variable, revealed no predictability role in the first three days of follow up for any of the variables included. However, during the fourth day of follow up, both WBC (OR = 0.261; 95% CI: 0.075, 0.908; p = 0.035) and lymphocyte percentage (OR = 1.074; 95% CI: 1.012, 1.141; p = 0.019) were marginally significant, in which increasing WBC was associated with a reduction in the likelihood of ANC count increase, compared to the lymphocyte percentage which exhibited an increase in the likelihood. In comparison, sequential ANC difference models demonstrated lymphocyte percentage (OR = 0.961; 95% CI: 0.932, 0.991; p = 0.011) and monocyte-to-lymphocyte ratio (OR = 7.436; 95% CI: 1.024, 54.020; p = 0.047) reduction and increment in the enhancement of ANC levels, respectively. The fifth day had WBC (OR = 0.790; 95% CI: 0.675, 0.925; p = 0.003) to be significantly decreasing the likelihood of ANC increment. Conclusions: we were unable to determine any concrete prognostic role of lymphocyte-related measures and ratios. It is plausible that several limitations could have influenced the results obtained, but as far as our analysis is concerned ALC role as a predictive factor for ANC changes remains questionable.

Genetic variation in the ADIPOQ gene and serum adiponectin increase the risk of bladder cancer.

Bladder cancer (BC) is the 10th most common cancer worldwide. Genetic studies estimated 30% heritability in BC risk. Adiponectin is an adipocytokine that has important roles in the regulation of energy metabolism. Recent evidence suggests dysregulation of adiponectin levels in BC tissues. Serum level of adiponectin is influenced by single nucleotide polymorphisms (SNPs) in the ADIPOQ gene. However, limited evidence is available regarding the association between adiponectin serum levels or SNPs in ADIPOQ and BC risk. This study aimed to assess whether adiponectin serum levels or SNPs in ADIPOQ may modify BC risk. In this case-control study, 114 BC patients were recruited along with 114 controls. Study subjects were genotyped for variations in ADIPOQ SNPs, namely rs17300539, rs266729, rs2241766, and rs1501299. Adiponectin levels were measured from the serum of study subjects. Our analysis showed that the G allele and the GG genotype of rs1501299 were significantly more frequent in BC patients compared to those in the control group (p-value < 0.05). Moreover, two ADIPOQ haplotypes containing the above G allele were associated with increased BC risk (p-value < 0.05). Multivariate analysis showed that increased serum adiponectin, smoking or age were all significant predictors of BC (p-value < 0.05). The data supports use of serum adiponectin and the G allele of rs1501299 SNP in ADIPOQ as potential biomarkers and/or targets in BC. To further validate findings in this study, larger populations of various ethnicities and/or genetic backgrounds are required. More investigations on the functional role of adiponectin in BC will also provide better understanding of potential targeting adiponectin for BC treatment.

Repeated microdissection testicular sperm extraction in patients with non-obstructive azoospermia: Outcome and predictive factors.

Objective: To assess the feasibility of repeated sperm recovery in patients with non-obstructive azoospermia (NOA), as little is known about the extraction rate in repeated microdissection testicular sperm extraction (microTESE) in these patients. Patients and Methods: A total of 134 men with NOA had their first sperm recovery between January 2013 and February 2020. Repeated microTESE had been done mostly for patients with a successful initial retrieval. Results: In the 323 procedures performed on the 134 men with NOA, sperm could be retrieved in 236 procedures (73.1%). A total of 88, 61 and 40 men underwent two, three and four sperm retrievals, respectively. In these cycles, sperm could be extracted in 65 (73.9%), 53 (86.9%) and 37 (92.5%) men, respectively. During the first microTESE procedure, sperm could be extracted in 81 (60.4%) men with NOA. In all, the success rate was significantly different between subgroups, showing highest rate in hypospermatogenesis cases (95.6%), followed by maturation arrest (58.5%), and Sertoli cell-only syndrome (56.0%). However, this difference was not significant at the third and fourth repeated microTESE. The FSH levels and testicular volume were among the noticeable factors affecting success of sperm retrieval. The duration between the first and second biopsies significantly increased the success rate by a factor of 1.3-fold/month; however, afterwards, the duration did not play any role in the success of microTESE. The success of previous trial significantly increased the probability of success by 10.1-fold in the second trial, 5.6-fold in the third trial, and 16.5 folds in the fourth. Conclusion: Repeated MD -TESE ensures a high sperm recovery rate in patients with NOA. These data also show that when no spermatozoa can be obtained after thawing cryopreserved testicular sperm for ICSI in NOA patients, a repeat microTESE procedure can be planned. Abbreviations: ICSI: intracytoplasmic sperm injection; IVF: in vitro fertilisation; MA: maturation arrest; (N)OA: (non-)obstructive azoospermia; OR: odds ratio; SCOS, Sertoli cell-only syndrome; SRR: spermatozoa retrieval rate; (micro)TESE: (microdissection) testicular sperm extraction.

The Effect of Transurethral Resection of the Prostate on Erectile and Ejaculatory Functions in Patients with Benign Prostatic Hyperplasia.

INTRODUCTION: The aim of this study was to investigate the effect of TURP on erectile function (EF) and ejaculatory function (EJF). METHODS: A total of 91 patients who underwent TURP were retrospectively assessed. Patients were divided into two groups based on International Index of Erectile Function (IIEF-5): group A included 41 patients with normal EF, and group B included 50 patients with erectile dysfunction (ED). All patients were evaluated for EF and EJF at baseline, 1, 3, and 6 months after TURP by using IIEF-5, Ejaculatory Domain-Male Sexual-Health Inventory (Ej-MSHQ). RESULTS: In group A, there were no significant statistical differences in mean IIEF-5 at baseline and after TURP 22.88 ± 0.81 versus 22.63 ± 2.63 (p = 0.065). However, in group B, there was significant improvement in IIEF-5 after TURP all over the follow-up time points in comparison to the baseline (p = <0.001). The loss of EJF was significant among patients in group A. There was significant improvement of IPSS and Qmax in group A after surgery compared to group B. CONCLUSION: The results confirmed that TURP has no significant negative influence on EF, and patients with preexisting ED were improved after TURP. On the contrary, the loss of EJF was significant.

Cervical tourniquet during cesarean section to reduce bleeding in morbidly adherent placenta: a pilot study.

Objective: To evaluate a modified surgical technique aiming to reduce bleeding and preserve fertility in morbidly adherent placenta by cervical tourniquet in cesarean sections. Methods: The cesarean section operations and the cervical ligation approach were performed by a single expert consultant obstetrician. The general demographics and clinical characteristics for all participants were collected and studied. Results: Eleven participants were involved. The uterus was preserved in nine patients, whereas two patients had hysterectomy. The mean blood loss was 1688.8 ml for patients whose uterus was preserved. The mean length of stay was 5.5 days. Conclusion: Cervical ligation is a simple method that can be applied by junior and experienced obstetricians to preserve the uterus.

A Comparative Study of the Respiratory Neonatal Outcomes Utilizing Dexamethasone Sodium Phosphate versus a Mixture of Betamethasone Dipropionate and Betamethasone Sodium Phosphate as an Antenatal Corticosteroid Therapy.

OBJECTIVE: The aim of this study is to compare the respiratory neonatal outcomes utilizing antenatal dexamethasone sodium phosphate (DSP) versus a mixture of betamethasone dipropionate and betamethasone sodium phosphate (B-DP/SP) for preterm births. PATIENTS AND METHODS: All neonatal intensive care unit (NICU) admissions for prematurity were retrospectively identified at our center in the period between September 2016 and September 2018. Pregnant women expected to give preterm birth and received steroid injections whether it is DSP or B-DP/SP were included in the study. Maternal and obstetrical data along with the corresponding respiratory neonatal outcomes were extracted and analyzed. The population was categorized according to the gestational age into extremely preterm (less than 28 weeks), very preterm (28 up to 32 weeks) and moderate or late preterm (32 up to 37 weeks) in which the repository outcomes were compared in each sub-group. RESULTS: A total of 650 premature neonates were included in the analysis. B-DP/SP illustrated a significant reduction in the occurrence of respiratory distress syndrome (RDS) among moderate or late preterm neonates (P = 0.003) compared to DSP. In contrast, a non-significant difference was observed between B-DP/SP and DSP regarding apnea of prematurity and transient tachypnea of the newborn. The number of neonates developed chronic lung disease has been remarkably reduced when using DSP in extremely (P = 0.038) and very (P = 0.046) preterm neonates when compared to B-DP/SP. CONCLUSION: The dual acting B-DP/SP formulation could possess a significant potential in reducing RDS in moderate or late preterm neonates, while DSP groups exhibit a favorable result in the development of chronic lung disease in extreme and very preterm cohorts. Such findings emphasize the need of further clinical trials, pharmacokinetics, pharmacodynamics and cost effectiveness studies to evaluate the durability of these findings.

Complete remission of advanced low-grade endometrial stromal sarcoma after aromatase inhibitor therapy: a case report.

BACKGROUND: Low-grade endometrial stromal sarcoma is a rare neoplastic growth in the uterine cavity, representing less than 1% of uterine tumors. Such tumors usually affect premenopausal and perimenopausal women, with a mean age of 46 years. Treatment generally starts with surgical resection of the tumor, followed by chemotherapy, radiotherapy, or hormonal therapy. CASE PRESENTATION: In the current report, we again present a case of low-grade endometrial stromal sarcoma in a 51-year-old Mediterranean woman presenting with abdominopelvic pain. Computed tomography scan revealed a primary uterine tumor measuring 17 × 9 × 9 cm metastasizing to the lungs, bladder, and ureteral orifice, along with lymphovascular involvement. The patient underwent total abdominal hysterectomy, omentectomy, and lymph node dissection. Estrogen deprivation was accomplished by bilateral salpingo-oophorectomy. Lifelong hormonal therapy consisting of letrozole 2.5 mg per day was prescribed, which demonstrated remarkable efficacy, resulting in a partial remission of lung metastasis within 8 months after surgery. Full remission was observed after 18 months of hormonal therapy, with no recurrence. Another scan was performed after 2.5 years, revealing complete remission with no recurrence. CONCLUSION: We again report a case of complete remission of low-grade endometrial stromal sarcoma after surgical removal of the tumor along with first-line hormonal therapy without the use of chemotherapy or radiotherapy, emphasizing the role of hormonal therapy in the treatment of such tumors.

Analysis of SLC7A9 gene mutations among Jordanian patients with cystinuria.

BACKGROUND: Cystinuria is known as a heritable disorder affecting the cysteine reabsorption by renal system as well as the reabsorption of dibasic amino acids. The main objectives of the present study were to identify genetic mutations in SLC7A9 gene associated with cystinuria. METHODS: A cross sectional study design was conducted. A total of 28 patients diagnosed with cystinuria were included. Molecular techniques were applied to identify genetic mutations in SLC7A9 gene. RESULTS: The mean age of study participants was 31.57 ± 2.88 years, and slightly more than two thirds of participants were males. Mutations of SLC 7A9 gene showed that the majority of cases (57.1%) were homogeneous, (7.1%) heterogeneous, and slightly more than one third of patients had no mutations. There was no statistically significant relationship between mutations for the SLC7A9 gene and gender (p = 0.249). CONCLUSION: Mutations in the SLC7A9 gene are prevalent and can be used as molecular tools to diagnose cystinuria.

Myxoma of the renal pelvis masquerading pelviureteric stenosis: conservative limited resection with renal preservation: case presentation and literature review.

BACKGROUND: Myxoma is a relatively rare mesenchymal tumor seen mainly in the heart and skin. Renal myxomas in particular are exceptionally rare where only 17 cases were previously reported in the English Language literature. Only 2 of the 17 reported cases were located in the renal sinus/pelvis. CASE PRESENTATION: This is a case of an 18-year-old male patient who complained of right, colicky flank pain associated with abdominal pain and discomfort. Imaging findings revealed right kidney hydronephrosis with a provisional diagnosis of pelviureteric junction (PUJ) stenosis. On computed tomography, there was a very faint thin walled mass abutting the calyces, camouflaged within the dilated renal pelvis. During surgery, a polypoid mass was found at the pelviureteric junction, causing the obstruction. Histological examination showed a hypocellular, paucivascular myxoid neoplasm, with few spindle cells displaying serpentine nuclei and inconspicuous nucleoli. The tumor cells expressed immunoreactivity for vimentin, but not for S100, CD34, actin, or desmin. This will qualify as the third case of renal pelvis myxoma. CONCLUSION: Myxomas in the renal pelvis/sinus are extremely rare and can present with hydronephrosis and subtle radiological findings mimicking a PUJ stenosis. Being aware of this entity can save the patient unnecessary nephrectomy with possible preservation of the kidney.

Adult-type granulosa cell tumor of the testicle: case report.

Granulosa cell tumor (GCT) is a sex-cord neoplasm of the gonads classified into either juvenile (jGrCT) or adult type (aGrCT). It is commonly arising in ovaries but is much rarer in men, with only around 50 male cases previously reported in the literature. We report on a 54-year-old male patient with a right testicular GCT measuring 10.0×8.0×6.0 cm. The tumor was treated successfully with radical orchiectomy followed by computed tomography to assess lymph node involvement, and no further treatment was done. Pathological reports showed diffuse positivity for immunohistochemical stains, inhibin, vimentin, calretinin, and CD99. The clinical and histopathological features, treatment, and prognosis of aGrCT arising in the testicle of an adult male are also reviewed in this manuscript.

Overactive bladder and associated psychological symptoms: A possible link to vitamin D and calcium.

INTRODUCTION: Overactive bladder (OAB) is a prevalent syndrome that is associated with multiple urinary tract symptoms and could affect the patient's quality of life and well-being. Vitamin D is shown to be linked to OAB syndrome, which exacerbated by stress conditions. This study evaluated the relationship between vitamin D status, daily calcium intake and OAB, and the associated psychological symptoms. METHODS: The study included 55 patients with OAB and 129 healthy controls. Psychological symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS). Serum vitamin D was measured. Patients with OAB with low vitamin D level received orally vitamin D supplementation. Urinary symptoms, psychological symptoms, and quality of life were evaluated before and after vitamin D supplementation plus dairy products. RESULTS: Vitamin D deficiency was more prevalent in cases (80%) vs controls (34.9%). Depression (43.7% vs 20.2%) and anxiety (52.8% vs 10.9%) scores (HADS, ≥8) were also more frequent in cases vs controls, respectively. Some 85.5% of the patients' group had musculoskeletal pain vs 0.0% for the control. Depression was negatively correlated with daily calcium intake and positively with anxiety. Logistic regression analysis revealed that age, vitamin D, and anxiety scores were significant predictors of OAB. Vitamin D supplements with increased calcium intake had significant improvement in urinary symptoms, psychological distress, and quality of life. CONCLUSIONS: Vitamin D supplements and improved calcium intake may improve urinary and psychological symptoms and quality of life among patients with OAB syndrome. Assessment for vitamin D status in patients with OAB may be warranted.

Single Large Bladder Stone in a Young Male Adult with Primary Hyperparathyroidism.

Bladder stones are caused when minerals are built up in the bladder, especially if the bladder is incompletely emptied. These stones will pass while they are small. Otherwise, they get stuck to the bladder wall or ureter. If this happens, they gradually gather more mineral crystals, becoming larger over time. Primary hyperparathyroidism is usually caused by a tumor within the parathyroid gland, and elevated calcium levels can cause digestive symptoms, psychiatric abnormalities, bone disease and multiple kidney stones.

Pancake Kidney Found Inside Abdominal Cavity: Rare Case with Literature Review.

The cake or lump kidney is a rare form of fusion. The pancake kidney is always found in the pelvic cavity, in the greater or lesser pelvis. However, we report a case of pancake kidney which was found inside abdominal cavity while investigating 32-year-old male for lower limb pain. CT scan with IV contrast reveals 'fused mass situated in the right side of abdominal cavity with course uncrossed ureters opening separately into the urinary bladder found incidentally with patient work up'. Pancake kidney in this case was managed conservatively without any complication. This malformation is usually present in pelvic cavity, so blood supply is almost constant but in rare cases might be different and follows location of this anomaly.

Upper Tract Urothelial Carcinoma in Ectopic Pelvic Kidney.

Upper tract urothelial carcinoma (UC) is an uncommon tumor. Ectopic kidney is also a rare entity. The combination of these two conditions is very rare. A 49-year-old male complained of right flank pain with hematuria. On CT scan he was found to have a malrotated right kidney with soft tissue seen in the upper calyceal group and a normal left kidney. Diagnostic cystoscopy was unremarkable. Radical nephroureterectomy with bladder cuff excision was performed. Pathology report revealed low grade urothelial carcinoma. Patient's symptoms disappeared postoperatively. Follow up showed no recurrence during the first two years in the bladder and upper tract in the contralateral kidney. Isolated UC of ectopic kidney is rare disease three cases were reported in literature. Although treatment of this tumor can be challenging due to its complex blood supply and position inside the pelvis, treatment strategy is still similar as for orthotopic kidneys.

Robot-assisted radical cystectomy and intracorporeal urinary diversion - safe and reproducible?

INTRODUCTION: Robot-assisted radical cystectomy (RARC) plus intracorporeal urinary diversion is feasible. Few centers worldwide demonstrated comparable functional and oncologic outcomes. We reported a large series of RARC and intracorporeal diversion to assess its feasibility and reproducibility. MATERIAL AND METHODS: We identified 101 RARCs in 82 men and 19 women (mean age 68.3 years) from October 2009 to October 2014. The patients underwent RARC and pelvic lymphadenectomy followed by intracorporeal urinary diversion (ileal conduit/ neobladder). Out of the 101 patients, 28 (27.7%) received intracorporeal ileal conduits and 73 (72.3%) intracorporeal neobladders. Studer pouch was performed in all the patients who underwent intracorporeal neobladder formation. Perioperative, functional and oncologic results including CSS and OS are reported. RESULTS: Mean operative time was 402.3 minutes (205-690) and blood loss was 345.3 ml (50-1000). The mean hospital stay was 17.1 days (5-62). All the surgeries were completed with no open conversion. Minor complications (Grade I and II) were reported in 27.7% of patients while major complications (grade III and above) were reported in 36.6% of patients. The mean nodal yield was 20.6 (0-46). Positive ureteric margins were found in 8.9% of patients. The average follow-up was 27.5 months (1-52). Daytime continence could be achieved in 89.2% of patients who underwent intracorporeal neobladder. The 3-year cancer specific survival (CSS) and overall survival (OS) was 80.2% and 69.8% respectively. CONCLUSIONS: RARC with intracorporeal diversion is safe and reproducible in 'non-pioneer' tertiary centers with robotic expertise having acceptable operative time and complications as well as comparable functional and oncologic outcomes.

Robot-assisted radical cystectomy and intracorporeal neobladder formation: on the way to a standardized procedure.

BACKGROUND: Robot-assisted radical cystectomy (RARC) with intracorporeal diversion has been shown to be feasible in a few centers of excellence worldwide, with promising functional and oncologic outcomes. However, it remains unknown whether the complexity of the procedure allows its duplication in other non-pioneer centers. We attempt to address this issue by presenting our cumulative experience with RARC and intracorporeal neobladder formation. METHODS: We retrospectively identified 62 RARCs in 50 men and 12 women (mean age 63.6 years) in two tertiary centers. Intracorporeal Studer neobladders were created, duplicating the steps of standard open surgery. Perioperative and postoperative variables and complications were analyzed using standardized tools. Functional and oncological results were assessed. RESULTS: The mean operative time was 476.9 min (range, 310 to 690) and blood loss was 385 ml (200 to 800). The mean hospital stay was 16.7 (12 to 62) days with no open conversion. Perioperative complications were grade II in 15, grade III in 11, and grade IV in 5 patients. The mean nodal yield was 22.9 (8 to 46). Positive margins were found in in 6.4%. The 90- and 180-day mortality rates were 0% and 3.3%. The average follow-up was 37.3 months (3 to 52). Continence was achieved in 88% of patients. The cancer-specific survival rate and overall survival rate were 84% and 71%, respectively. CONCLUSIONS: A RARC with intracorporeal neobladder creation is safe and reproducible in 'non-pioneer' tertiary centers with robotic expertise with acceptable operative time and complications. Further standardization of RARC with intracorporeal diversion is a prerequisite for its widespread use.
