Endopelvic Fascia Sparing Robotic Radical Cystectomy with Intracorporeal Studer Pouch with Balbay's Technique.

Background and Objectives: Robotic radical cystectomy (RARC) with intracorporeal urinary diversion is a technically complicated, time-consuming procedure. The aim of this study was to present the operative, pathological, oncological, and functional outcomes of patients who underwent endopelvic fascia sparing (EPFS) RARC with intracorporeal Studer pouch formation. To the best of our knowledge, this is first series in the literature that includes EPFS RARC. Methods: Between October 1, 2019 and April 30, 2022, 10 bladder cancer patients underwent EPFS RARC, bilateral extended pelvic lymph node dissection with intracorporeal Studer pouch reconstruction with Balbay's technique. Patient demographics, operative, and post-operative parameters were recorded. Results: Among 10 patients, 8 were male and 2 were female. Mean operative time, median estimated blood loss, and median duration of hospital stay was 530 minutes, 316 ml, and 8 days, respectively. One month postoperatively, the mean maximum flow, average flow rate, mean voided, and post-voided urine volume were 20.2 ml/sec, 4.4 ml/sec, 273.6 ml, and 3.5 ml, respectively. All of the patients were fully continent during day-time, three had mild night-time incontinence requiring pad use (both patients 1 pad per night). During a mean 11.5 months of follow up, zero patients died. One patient with a pathological, stage 4 tumor, had nodal recurrence at six months postoperatively. No distant metastasis were detected. Conclusion: Endopelvic fascia sparing RARC has very promising early functional results with safe oncological outcomes and low complication rates.

The clinical impact of Prostate Imaging-Reporting and Data System classification in patients with haemospermia undergoing multiparametric magnetic resonance imaging of the prostate.

In this study, we evaluated the role of the Prostate Imaging-Reporting and Data System (PI-RADS) classification of multiparametric magnetic resonance imaging (mpMRI) to determine the likelihood of prostate cancer (PCa) in patients with haemospermia. Fifty-one patients presenting with haemospermia between 2018 and 2020 were included in this retrospective study. Forty-two of the patients (82.4%) were over 40 years, and the median prostate-specific antigen (PSA) level was 1.4 ng/ml. Fourteen of the patients (27.5%) had recurrent haemospermia. All patients underwent mpMRI, and assessments were classified according to PI-RADS v2. The mpMRI revealed PI-RADS one to four lesions in 10 (19.6%), 30 (58.8%), 6 (11.8%) and 5 (9.8%) patients respectively. One patient with PI-RADS 3 and five with PI-RADS 4 lesions underwent cognitive fusion prostate biopsy depending on MRI findings, and two patients with PI-RADS 4 lesions were diagnosed with PCa. Patients with haemospermia and risk factors, that is aged over 40 years, a high PSA level or familial history of PCa, need a more thorough evaluation with mpMRI.

Comparison of the trifecta outcomes of robotic and open nephron-sparing surgeries performed in the robotic era of a single institution.

PURPOSE: In this study we aimed to report a comparative analysis between open and robotic nephron sparing surgeries (NSS) from a single institutional database. METHODS: Patients who have undergone NSS during the robotic era of our institution were included in this study. Open (n = 74) and robotic (n = 59) groups were compared regarding trifecta outcome. Trifecta was defined as; warm ischemia time (WIT) <25 min, negative surgical margins and the absence of perioperative complications. RESULTS: A total of 57 (77 %) and 45 (76 %) patients in the open and robotic groups, respectively achieved the trifecta outcome. Overall trifecta rate was 77 % (n = 102/133). The only statistically significant difference between trifecta positive and trifecta negative patients was the length of hospitalization (LOH). Except LOH; none of the tested parameters were shown to be predictive of trifecta outcome on univariate and multivariate analyses. Concerning trifecta positive patients; those in the open surgery group had larger tumors with a higher degree of morphometric complexity and were hospitalized for a longer period of time. Additionally, operative duration was significantly higher in the robotic group. CONCLUSIONS: In our cohort, no significant difference in achieving the trifecta outcome was reported after open and robotic NSS. Length of hospitalization was the only parameter that differed significantly between trifecta positive and trifecta negative patients. Surgical approach was not a significant predictor of simultaneous achievement of trifecta outcomes. Irrespective of the trifecta definition; larger and more complicated tumors were handled via open NSS.

Do we need to clamp the renal hilum liberally during the initial phase of the learning curve of robot-assisted nephron-sparing surgery?

OBJECTIVE: We aimed to compare the results of our initial robot-assisted nephron-sparing surgeries (RANSS) performed with or without hilar clamping. MATERIAL AND METHOD: Charts of the initial RANSSs (n = 44), which were performed by a single surgeon, were retrospectively reviewed. R.E.N.A.L. nephrometry system, modified Clavien classification, and M.D.R.D. equation were used to record tumoral complexity, complications, and estimated glomerular filtration rate (eGFR), respectively. Outcomes of the clamped (group 1, n = 14) versus off-clamp (group 2, n = 30) RANSSs were compared. RESULTS: The difference between the two groups was insignificant regarding mean patient age, mean tumor size, and mean R.E.N.A.L. nephrometry score. Mean operative time, mean estimated blood loss amount, and mean length of hospitalization were similar between groups. A total of 4 patients in each group suffered 11 Clavien grade ≥ 2 complications early postoperatively. Open conversion rates were similar. The difference between the 2 groups in terms of the mean postoperative change in eGFR was insignificant. We did not encounter any local recurrence after a mean follow-up of 18.9 months. CONCLUSIONS: Creating warm-ischemic conditions during RANSS should not be a liberal decision, even in the initial phases of the learning curve for a highly experienced open surgeon.

Port site and peritoneal metastases after robot-assisted radical prostatectomy.

INTRODUCTION: Port site metastasis after minimally invasive urologic surgery is a rare event despite the widespread utility of laparoscopic techniques in the management of urologic malignancies. Herein, we report a case of port site metastasis after robot-assisted radical prostatectomy. PRESENTATION OF CASE: A currently 77-year-old male patient, who was diagnosed with cT2c, Gleason 7 (4+3) prostate adenocarcinoma in our clinic back in 2009, had undergone robot-assisted radical prostatectomy elsewhere. Histopathological examination revealed pT3a, Gleason 9 (4+5) disease. Lymph nodes were negative, however surgical margins were positive on the right side. PSA recurred after 9 months and maximal androgen blockade was initiated. Despite antiandrogenic manipulations, PSA reached 0.83ng/ml, 33 months postoperatively. Concurrently, we noticed a palpable anterior abdominal mass which demonstrated metabolic hyperactivity on PET scanning. Percutaneous biopsy of the lesion confirmed the presence of metastatic adenocarcinoma. PSA did not normalize after the complete excision of the metastatic focus. Repeated PET scan revealed multiple implants on the peritoneal surfaces of various organs. DISCUSSION: Port site and peritoneal metastasis of prostate cancer after robot-assisted radical prostatectomy has not been reported so far. This peculiar dissemination pattern is most probably the result of tumor biology and perioperative factors. CONCLUSION: Although encountered extremely rarely, surgeons should be aware of the possibility of port site and/or peritoneal metastases after minimally invasive radical prostatectomy.

Morphometric profile of the localised renal tumors managed either by open or robot-assisted nephron-sparing surgery: the impact of scoring systems on the decision making process.

BACKGROUND: Nephrometric scoring systems aim to improve the manner in which tumoral complexity is measured and reported. Each system provides a way to objectively measure specific tumor features that influence technical feasibility. In this study we aimed to determine how nephrometric scoring systems tailored our approach to the surgical treatment of localised renal masses. METHODS: Charts of the patients with localised renal tumors, who were managed by either open or robot-assisted nephron-sparing surgery between May 2010 and June 2012, were retrospectively reviewed. Nephrometric scores [radius, exophytic/endophytic, nearness, anterior/posterior, location (R.E.N.A.L.) score, preoperative aspects and dimensions used for anatomic (P.A.D.U.A.) classification and centrality index (C-index)] were calculated based on preoperative imaging findings. Perioperative data were recorded. Morphometric characteristics of the renal masses were compared. Additionally, the difference between surgical alternative subgroups in terms of morphometric variables and the predictive power of each scoring system in determining the details of the surgical plan were investigated. Furthermore, surgical preferences in different nephrometric categories were compared. RESULTS: Mean R.E.N.A.L. and P.A.D.U.A. scores of the tumors treated with robotic surgery were significantly lower than those managed by open surgery. R.E.N.A.L. nephrometry score showed significant differences between most of the surgical alternative subgroups. P.A.D.U.A. and C-index differences were significant only between robotic off-clamp and open clamped cases. Tumors that required open conversion had significantly higher mean R.E.N.A.L. and P.A.D.U.A. score. High R.E.N.A.L. score (cut-off: 6.5) and high P.A.D.U.A. score (cut-off: 7.5) were found to be significant predictors of the surgical route. Significantly more tumors with moderate R.E.N.A.L. score were managed through the open approach, while the significant majority of those with low R.E.N.A.L. and low P.A.D.U.A. score were operated by robotic assistance. CONCLUSIONS: R.E.N.A.L. and P.A.D.U.A. scores influenced our surgical treatment strategy for localized renal masses. High R.E.N.A.L. and P.A.D.U.A. scores increased the likelihood of an open NSS.

Nonleukemic ureteral granulocytic sarcoma presenting with unilateral urinary obstruction and hematuria.

Granulocytic sarcoma is an extramedullary tumor which is composed of myeloblasts and immature myeloid cells. It usually occurs in association with acute myeloid leukemia and most commonly involves skin, soft tissue, lymph nodes, bone, and periosteum. We report a case of isolated ureteral granulocytic sarcoma without hematologic manifestations. Our patient presented with bloody urine and left-sided lumbar pain. Preoperative clinical and radiologic features raised the suspicion of an upper urinary tract transitional cell carcinoma, and he was scheduled for nephroureterectomy. However, perioperative pathologic feedback and the unusual endoscopic appearance of the tumor altered our surgical strategy towards segmental ureterectomy and ureteroneocystostomy. Eventual pathologic diagnosis was granulocytic sarcoma of the ureter. Postoperative workup failed to demonstrate any sign of an accompanying hematologic disorder. He started receiving the chemotherapy protocol of acute myeloblastic leukemia. To our knowledge, this is the first documented case of nonleukemic ureteral granulocytic sarcoma which came to attention due to urologic complaints.

Nephron-Sparing Surgery for Renal Masses Measuring Larger Than 7 cm on Preoperative Imaging: A Single Surgeon, Single Center Experience.

Objectives. To document the feasibility of nephron-sparing surgery (NSS) for the surgical treatment of renal masses measuring larger than 7 cm (cT2) on preoperative imaging. Methods. A total of 139 patients have undergone NSS between 2001 and 2012 by a single surgeon in our clinic. Of these, we identified 17 patients whose tumors were measuring greater than 7 cm on preoperative imaging studies and were limited to the kidney. Their charts were retrospectively reviewed. Results. Mean age of the study population was 49.8 ± 11.3 years. Thirteen patients were managed by open NSS, while 4 patients have undergone robot-assisted NSS. Mean diameter and mean R.E.N.A.L. score of the tumors that were enucleoresected were 8.2 cm and 8.5, respectively. A total of 5 Clavien grade 2 and higher complications were recorded within 30 days of surgery. Histopathologic examination revealed benign histology in almost 1/4 of the cases. After a median followup of 33 months, all of our patients were alive. Only one patient (5.8%) experienced local recurrence. Conclusions. NSS is a feasible and safe option for large (>7 cm) renal masses. It may be considered not only for imperative conditions but also for highly selected cases with a normal contralateral kidney.

Adrenal cortex-sparing surgery for bilateral multiple pheochromocytomas in a patient with von hippel-lindau disease.

Pheochromocytomas can be a part of familial neoplastic syndromes, in which case they tend to be multiple and involve both adrenal glands. Therefore, sparing adrenocortical function represents a major concern while dealing with these hereditary lesions. Herein, we describe the clinical characteristics and the management strategy of a patient with von Hippel-Lindau (VHL) disease who had multiple, bilateral pheochromocytomas as well as bilateral renal masses, pancreatic masses, and a paracaval mass. Only a portion of the left adrenal gland has remained in situ after two consecutive open surgeries and a percutaneous radiofrequency ablation which have been performed to treat the various components of this syndrome. No adrenal or extra-adrenal pheochromocytoma recurrences have been detected during a follow-up period of more than 2 years. Pancreatic and adrenal functions were normal throughout the postoperative period and never necessitated any replacement therapy. Adrenal cortex-sparing surgery is a valid option for VHL disease patients who present with synchronous bilateral adrenal pheochromocytomas.

Malignant mesothelioma of the tunica vaginalis: presenting with intermittent scrotal pain and hydrocele.

Paratesticular mesotheliomas are very rare tumors. In this paper, we present the management of a 38-year-old male patient with paratesticular malignant mesothelioma who was initially misdiagnosed and treated as recurrent epididymitis. After the final pathology report defining paratesticular mesothelioma during scrotal exploration, he underwent radical orchiectomy and hemiscrotal excision as a complementary, secondary procedure. His metastatic workup did not show any dissemination. Therefore, he did not receive any adjuvant treatment and remained disease-free for more than 2 years.

Staged, open, no-ischemia nephron-sparing surgery for bilateral-multiple kidney tumors in a patient with birt-hogg-dubé syndrome.

Hereditary kidney cancer patients with bilateral multiple kidney tumors represent challenges in the era of rapidly growing minimal invasive treatment techniques. Birt-Hogg-Dubé Syndrome (BHDS) is an autosomal dominant genodermatosis characterized by a triad of benign skin tumors (fibrofolliculomas, trichodiscomas, acrochordons) together with an increased risk of developing malignant renal tumors and pulmonary disease such as pneumothoraces and multiple lung cysts. The morbidity and mortality of the affected patients is determined by the presence of the kidney tumors, which tend to be multifocal and bilateral, as observed in other hereditary kidney cancer syndromes like von Hippel-Lindau disease, familial leiomyomatosis, and hereditary papillary renal cell carcinoma. Herein, a patient with BHDS, presenting with synchronous bilateral multiple kidney tumors, is reported. The report describes the management of kidney tumors with two-stage open nephron-sparing surgery in which the nonvascular clamping technique was utilized.
