Renal Function Preservation in Purely Off-Clamp Sutureless Robotic Partial Nephrectomy: Initial Experience and Technique.

The aim of our study is to evaluate the effectiveness and safety of a sutureless off-clamp robot-assisted partial nephrectomy (sl-oc RAPN), particularly its impact on renal function. A multicenter study was conducted from April 2021 to June 2022. Patients diagnosed with a renal mass of >2 cm and a PADUA score of ≤6 consecutively underwent an sl-oc RAPN procedure. Tumor features, patients characteristics, and intraoperative outcomes were assessed. An evaluation of renal function was performed preoperatively, and again at 1 and 3 months after surgery by measuring the creatinine and blood urea nitrogen levels. The renal function of the two separate kidneys was assessed by a sequential renal scintigraphy performed before and at least 30 days after surgery. A total of 21 patients underwent an sl-oc RAPN. The median age was 64 years (IQR 52/70), the median tumor diameter was 40 mm (IQR 29/45), and the median PADUA score was 4 (3.5/5). The intraoperative outcomes included operative time (OT), 90 (IQR 74/100) min; estimated blood loss (EBL), 150 (IQR 50/300) mL; and perioperative complications, CD > 3 1(5%); only two patients presented positive surgical margins in their final histology (2/21, 10%). Compared to the preoperative value, a decrease in renal function was highlighted with a statistically significant median decrease of 10 mL/min (p < 0.01). The renal scintigraphy showed an overall decrease in renal function compared to the preoperative value, with a range in the operated kidney that varied from 0 to 15 mL/s and from 0% to 40%, with a median value of 4 mL/s and 12%. sl-oc RAPN is a safe procedure, with a minimal impact on kidney function alteration. This technique has proven effective in preserving renal function and maintaining optimal oncological outcomes with limited complications.

Comparing robotic and open partial nephrectomy under the prism of surgical precision: a meta-analysis of the average blood loss rate as a novel variable.

Exploration of surgical precision in robotic procedures is extensive, yet lacks a unified framework for comparability. This study examines tissue handling precision by comparing the per-minute blood loss rate between robotic and open partial nephrectomy. A literature search from August 2022 to June 2024 identified 43 relevant studies providing data on estimated blood loss and procedure duration. The expected values and standard errors of these variables were used to compute the per-minute blood loss rate (Q). Meta-analytical methods estimated pooled and subgroup-level mean differences, favoring robotic surgery (MDQ = - 1.043 ml/min, CI95% = [- 1.338; - 0.747]). Subgroup analyses by publication year, patient matching, referral center count, and ROBINS-I status consistently supported this advantage. Sensitivity analyses confirmed the above benefit in studies with increased accuracy in reported results (MDQ = - 0.957 ml/min, CI95% = [- 1.269; - 0.646]), low risk of bias involving matched comparisons (MDQ = - 0.563 ml/min, CI95% = [- 0.716; - 0.410]), large sample sizes and increased statistical power (MDQ = - 0.780 ml/min, CI95% = [- 1.134; - 0.425]), and multicenter analyses with patient matching (MDQ = - 0.481 ml/min, CI95% = [- 0.698; - 0.263]). The subsequent analysis of correlation between the original variables suggested a slight reduction in the robotic advantage when the latter were proportionally related. Multilevel meta-regression at both temporal and qualitative scales consistently indicated a comparative benefit of the robotic approach. Potentially, lower per-minute blood loss compared to open surgery suggests that robotic partial nephrectomy demonstrates enhanced precision in tissue handling.

[Clinicopathological characteristics and prognosis of multilocular cystic renal neoplasm of low malignant potential].

OBJECTIVE: To analyze the clinicopathological characteristics and prognosis of patients with multilocular cystic renal neoplasm of low malignant potential and compare the clinicopathological characteristics of patients with multilocular cystic renal neoplasm of low malignant potential who underwent different surgical methods. METHODS: Clinicopathological data and prognosis of patients admitted to Peking University Third Hospital from January 2010 to September 2023 were collected. Patients who underwent radical nephrectomy or nephron-sparing surgery and were pathologically diagnosed with multilocular cystic renal neoplasm of low malignant potential were identified. Based on the surgical methods, the patients were divided into radical nephrectomy group and nephron-sparing surgery group. The clinicopathological characteristics of the two groups were compared. RESULTS: A total of 35 patients were enrolled in this study. The median age at diagnosis was 53.0 (39.0-62.0) years. Among the 35 patients, 23 were males (65.7%) and 12 were females (34.3%). Nine patients underwent radical nephrectomy (25.7%), while 26 patients underwent nephron-sparing surgery (74.3%). The clinical T-stage of 35 patients did not exceed T2a stage. The median operation time was 145.0 min, and the median estimated intraoperative blood loss was 20.0 mL. The median postoperative hospitalization days was 6.0 d. The postoperative pathological results did not indicate renal sinus invasion, sarcomatous change, adrenal invasion or lymph node invasion. Based on the surgical methods, the patients were divided into a radical nephrectomy group and a nephron-sparing surgery group. There was no significant difference in clinicopathological charac-teristics between the two groups. Except for one patient who was lost to the follow-up, all the other patients were followed up for 8-111 months, with a median follow-up time of 70.5 months. Only one patient died from non-cancer-specific reasons, other patients had no tumor metastasis or recurrence. CONCLUSION: Patients with multilocular cystic renal neoplasm of low malignant potential have a good prognosis. There is no significant difference in clinicopathological characteristics of patients between nephron-sparing surgery group and radical nephrectomy group for multilocular cystic renal neoplasm of low malignant potential.

Health-related quality of life, sexual function, psychological health, reproductive concerns and fertility outcome in young women treated with fertility-sparing surgery for ovarian tumors - A prospective longitudinal multicentre study.

OBJECTIVE: This study aimed to investigate health-related quality of life (HRQoL), sexual function, psychological-health, reproductive concerns, and fertility outcomes of women of reproductive age undergoing Fertility-Sparing Surgery (FSS) for treatment of ovarian cancer (OC) or borderline ovarian tumor (BOT), over a 2-year period. METHODS: Prospective longitudinal multicentre study including women 18-40 years undergoing FSS between 2016 and 2018 in Sweden. Clinical data at diagnosis, histopathological findings and 2-year follow-up regarding oncological and reproductive outcomes were collected. Participants completed the EORTC QLQ-C30 and OV-28, FSFI, HADS and study-specific items at time of diagnosis and at one- and two-years following FSS. Data were analysed using a model for repeated measures to investigate changes over time. RESULTS: Of 68 eligible women, 49 were included following exclusions due to benign pathology or subsequent radical surgery. During a mean follow-up of 20.5 months, two women experienced a recurrence and 82% reported regular menstruations. The majority (94%) had a strong desire to become biological mothers, which remained or increased over time. The conception-rate was 76%. HRQoL, psychological-health and sexual function improved over time and the proportion of women with sexual dysfunction decreased. At one-year follow-up 50% of nulliparous women had scores indicating sexual dysfunction compared to 0% of the women who had given birth either before or after surgery (p = 0.008). CONCLUSION: HRQoL, psychological-health and sexual function improved during two-year follow-up after FSS in young women presenting with OC or BOT. Women who had given birth prior to or after FSS reported improved sexual function compared to nulliparous women.

Management guidelines for incidental uterine surgery in early pregnancy: a case report of a robotic myomectomy at 4 weeks gestation after a false-negative pregnancy test.

Objective: To share our case and offer guidance to practitioners on the management of incidental uterine surgery in early pregnancy. Although elective uterine surgery should be avoided during pregnancy, there is always a chance of undetected pregnancy at the time of surgery, even after all precautions have been taken. There is currently minimal literature on the management and outcomes of uterine surgery during pregnancy. Design: Case report. Setting: University Hospital. Patient: A 42-year-old G1P1 female with symptomatic fibroids desiring fertility-sparing surgery was retroactively found to be 4 weeks pregnant at the time of surgery, even after a negative pregnancy test and low suspicion for pregnancy under Centers for Disease Control and Prevention guidelines. Intervention: Robotic-assisted laparoscopic myomectomy performed with a false-negative urine pregnancy test at the time of surgery. Main Outcome Measures: Guidance for surveillance and management options during continued pregnancy after robotic uterine surgery and cavity disruption by a uterine manipulator performed at 4 weeks gestation that went undetected at the time of surgery. Results: The patient was able to undergo an uncomplicated delivery by cesarean section at 38 weeks and delivered a healthy infant. Conclusion: Using a multidisciplinary approach, we describe guidelines for antepartum surveillance uterine surgery during an undetected pregnancy, which resulted in the delivery of a term healthy infant.

Right uniportal video-assisted thoracoscopic surgery lung-sparing sleeve resection of the bronchus intermedius

Complete surgical resection has been the main treatment modality for pulmonary neoplasms without locoregional or distant spread of the disease. Sleeve resections were developed to minimize unnecessary loss of pulmonary parenchyma mainly in the case of centrally located tumours. Experience with sleeve resections and recent technological advancements made minimally invasive resection possible for selected patients. We present a case report of the totally thoracoscopic uniportal sleeve resection of the bronchus intermedius without any resection of pulmonary parenchyma. The operation was performed successfully, and the patient did not experience any postoperative complications. In this case report, we describe our surgical approach and short-term results.

Nerve-sparing surgery in deep endometriosis: Has its time come?

Nerve-sparing (NS) surgery was first introduced for the treatment of deep endometriosis (DE) 20 years ago, drawing on established neuroanatomy and success from oncological applications. It aims to identify and preserve autonomic nerve fibres, reduce iatrogenic nerve injury, and minimize postoperative visceral dysfunction, without compromising the therapeutic effectiveness against endometriosis. The evolution of NS surgical techniques over the past two decades has been supported by an expanding body of literature on anatomical details, dissection techniques, and functional outcomes. Recent evidence suggests that NS surgery results in reduced postoperative voiding dysfunction (POVD). Transient POVD may be influenced by preoperative dysfunction, with parametrial infiltration being a strong predictive factor for POVD. While the benefits in bowel and sexual functions are less pronounced and consistent, NS surgery potentially prevents de novo dysfunctions in these areas. Furthermore, perioperative complication rates, effectiveness in pain relief, and fertility outcomes are reportedly on par with conventional surgery.

Navigating the Aftermath: A Comprehensive Scoping Review on Follow-up Strategies After Kidney-sparing Surgery for Upper Tract Urothelial Carcinoma.

Background and objective: Upper tract urothelial carcinoma (UTUC) can be managed efficiently and safely through kidney-sparing surgery (KSS) in selected patient groups. However, the most effective and efficient postoperative surveillance strategy remains undetermined. We aimed to provide a comprehensive synopsis of the follow-up strategies and survival outcomes in patients diagnosed with UTUC treated by KSS. Methods: Following the systematic methodology outlined in the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension for Scoping Reviews, we conducted searches in four databases (MEDLINE [Ovid], Embase [Ovid], Cochrane Library, and Web of Science) up until December 11, 2023. Key findings and limitations: A total of 3121 articles underwent screening, of which 19 were selected for inclusion in this review. The follow-up schedules after KSS exhibited considerable variability among the included studies. Diagnostic modalities employed consisted of computed tomography urography (present in 84% of protocols), X urography (21%), ultrasound (21%), thoracic imaging (26%), voided urine cytology (89%), selective upper tract cytology (5.3%), cystoscopy (84%), and ureterorenoscopy (53%) at varying frequencies. At 5 yr of follow-up, the reported recurrence-free survival rate ranged from 30% to 86%, overall survival was 50-92%, and metastasis-free survival was 77-90%. Conclusions and clinical implications: This review unveils significant heterogeneity in clinical practices and survival outcomes, indicating disparities between real-world approaches and guideline recommendations. The lack of consensus on follow-up schemes is evident, emphasising the necessity for future initiatives aimed at developing a comprehensive protocol. Patient summary: This review shows significant heterogeneity in follow-up strategies after kidney-sparing surgery for upper tract urothelial carcinoma. A lack of evidence contributes to discrepancies between guidelines and real-world approaches. Thus, future endeavours should aim at establishing a comprehensive protocol.

Wilms tumor characteristics, surgical management, outcomes, and chronic kidney disease in children with WAGR syndrome: A report from the International WAGR Syndrome Association survey.

INTRODUCTION: Children with WAGR (Wilms tumor, aniridia, genitourinary anomalies, and range of development delays) syndrome are predisposed to Wilms tumor (WT) and intrinsic kidney disease. Using the comprehensive International WAGR Syndrome Association (IWSA) survey of children with WAGR syndrome, we analyzed tumor characteristics, treatment and congenital risk factors, and kidney function in children with WAGR and WT. METHODS: Descriptive statistics were utilized including demographics, treatment strategies, and patient outcomes. Comparisons were made between patients with WAGR and WT to those with WAGR alone. A multivariable logistic regression was completed for risk of developing WT and to identify predictors of chronic kidney disease (CKD). RESULTS: Sixty-four of 145 children with WAGR developed WT (44.1%). Three relapsed and one died. CKD developed in five children with WAGR without WT (5/81, 6.2%), and in 34 with WAGR and WT (34/64, 28.3%). Children with WAGR and WT were younger (p = .017), and had a greater association with CKD than WAGR children without WT (p < .0001). Two children with WT required hemodialysis, and one underwent kidney transplantation. By univariate analysis, CKD at any stage was associated with complete nephrectomy for the WT surgery (p < .0001), chemotherapy duration greater than 12 months, and three-drug therapy. Upon multivariate analysis, prior nephrectomy was the only significant variable (p = .0002). CONCLUSIONS: Epidemiological analysis of children with WAGR demonstrated favorable oncologic outcomes, but high rate of early CKD in those who developed WT. Further study of the use of nephron-sparing surgery in children with WAGR and strategies to delay or treat early CKD are needed.

Multiparametric Ultrasound for Focal Testicular Pathology: A Ten-Year Retrospective Review.

Conventional ultrasonography (US), including greyscale imaging and colour Doppler US (CDUS), is pivotal for diagnosing scrotal pathologies, but it has limited specificity. Historically, solid focal testicular abnormalities often led to radical orchidectomy. This retrospective study evaluated the utilisation of contrast-enhanced ultrasound (CEUS) and strain elastography (SE) in investigating intratesticular focal abnormalities. A total of 124 cases were analysed. This study underscored the superior diagnostic capabilities of CEUS in detecting vascular enhancement in all malignant cases, even those with undetectable vascularity by CDUS. It also highlighted the potential of CEUS in identifying distinctive vascular patterns in benign vascular tumours. Definitive confirmation of benignity could be obtained when the absence of enhancement was demonstrated on CEUS. While SE alone offered no distinctive advantage in differentiating between benign and malignant pathologies, we demonstrated that incorporating a combination of CEUS and SE into the evaluation of focal testicular abnormalities could improve diagnostic performance metrics over conventional CDUS. Our findings underscore the role of advanced ultrasound techniques in enhancing the evaluation of focal testicular abnormalities in clinical practice and could aid a shift towards testis-sparing management strategies.

Does bilateral Wilms' tumor involving the collecting system in children have a worse prognosis?

BACKGROUND: The literature on nephron-sparing surgery (NSS) in children with bilateral Wilms' tumors (BWT) involving the collection system is mostly comprised of case reports. The present study aimed to summarize the clinical characteristics, treatments, and prognosis of children with BWT involving the collecting system admitted to our pediatric surgery center compared with those whose tumors did not involve the collecting system. A secondary aim was to discuss how to preserve more kidney parenchyma and prevent long-term renal failure under the premise of preventing tumor recurrence. METHODS: Patients with BWT admitted to our pediatric surgery center between January 2008 and June 2022 were reviewed. All included patients were grouped according to the relationship between the tumor and collecting system according to the intraoperative findings. Group I included children with tumor infiltrating the collecting system, group II included children with tumor growing into the collecting system, and group III included children whose tumor did not involve the collecting system. The clinical features, treatments and prognosis of the patients were analyzed. RESULTS: Seventy patients were enrolled, including 20 patients with 25 sides of tumors infiltrating the collecting system in group I,10 patients with 13 sides of tumors growing into the collecting system in group II, and 40 patients in group III. There was no significant difference in patients age and gender between group I and group II. In total, 20 patients in group I and 9 patients in group II had partial response (PR) after neoadjuvant chemotherapy. In group I, 22 of 25 sides of tumors underwent NSS; in group II, 11 of 13 sides of tumors underwent NSS. During an average follow-up of 47 months, in group I, 6/20 patients relapsed and 2/20 patients died; in group II, 3/10 patients relapsed and 1/10 patient died. There was no significant difference in 4-year overall survival (OS) rate among groups I, II and III (86.36% vs. 85.71%vs. 91.40%, P = 0.902). CONCLUSIONS: To preserve renal parenchyma, NSS is feasible for children with BWT involving the collecting system. There was no significant difference in postoperative long-term OS between patients with BWT involving the collecting system and not involving the collecting system.

Nerve-sparing deep endometriosis surgery with rectal discoid resection using da Vinci SP.

OBJECTIVE: To demonstrate the anatomical and technical highlights of nerve-sparing deep endometriosis (DE) surgery with rectal discoid resection using a newer single-port robotic system. DESIGN: Step-by-step demonstration of this method was provided with narrated video footage. SETTING: The surgery was performed at an urban general hospital. Single-port laparoscopic surgery is a useful surgical approach in gynecology because of the excellent cosmetic results but shows challenges including reduced intracorporeal triangulation and conflict with nonarticulating instruments. The range of indications is thus limited. PATIENT: A 46-year-old woman was referred with severe pelvic pain, dysmenorrhea, and pain on defecation. Magnetic resonance imaging revealed uterine adenomyosis, bilateral ovarian endometriomas, and 3 cm of rectal endometriosis. Computed tomography colonography confirmed 38% stenosis of the rectum. INTERVENTION: A newer single-port robotic system was used. MAIN OUTCOME MEASURES: The main outcome measures were technical safety and feasibility of intrapelvic complex DE surgery using a newer single-port robotic platform. RESULTS: The procedure was performed using nine steps with a da Vinci SP surgical system (Intuitive Surgical, Sunnyvale, California). Importantly, the surgical steps were completely identical to conventional multiport laparoscopic or robotic surgery. This suggests that conventional laparoscopic or robotic skills are highly transferrable to the newer system. The surgical steps are as follows: The newer single-port system offered several advantages, including high-resolution three-dimensional visualization, articulating instruments (intracorporeal instrument triangulation), and improved dexterity and range of motion. These advantages allow precise dissection even in difficult situations such as DE. CONCLUSIONS: This appears to be the first reported use of the da Vinci SP for nerve-sparing DE surgery or rectal discoid resection. The newer single-port robotic system can provide the same quality of surgery as conventional multiport laparoscopic and robotic platforms with cosmetic advantages for the treatment of complex pelvic pathologies.

Laparoscopic-assisted fertility-sparing surgery for growing teratoma syndrome of the ovary: experience from a tertiary center.

STUDY OBJECTIVE: The main objective is to evaluate the feasibility of laparoscopic fertility-sparing surgery in women with growing teratoma syndrome. DESIGN: Retrospective cohort study. SETTING: Chinese tertiary university hospital. PATIENTS: Patients with growing teratoma syndrome who underwent fertility-sparing surgery between January 2015 and August 2023. INTERVENTIONS: Baseline characteristics and surgical outcomes were evaluated, including clinical information, surgical procedures, operative time, intraoperative blood loss, complications, length of hospital stay, and follow-up information. MEASUREMENT AND MAIN RESULTS: Twenty-six patients with ovarian growing teratoma syndrome underwent fertility-sparing surgery: 12 had laparoscopic surgery and 14 underwent laparotomic surgery. In the laparoscopic group, the median age of the patients during initial management of immature teratoma or mixed malignant ovarian germ cell tumor was 14.0 years (interquartile range: 13.0-24.5 years). Eleven patients were nulliparous. The primary ovarian tumor was pure immature teratoma in 10 patients and mixed ovarian germ cell tumor in 2 patients. Complete laparoscopic tumor resection was achieved in 11 patients. Patients in laparoscopic group had shorter median operative time (76.5 vs 180.0 minutes, p = 0.001), lower estimated blood loss (20.0 vs 400.0 ml, p < 0.001), decreased postoperative hospital stay (2.0 vs 7.0 days, p < 0.001), compared with laparotomic surgery. There was no conversion to laparotomy and no perioperative complications. Histological examination confirmed mature teratoma in all cases. During a median follow-up of 21.9 months (interquartile range: 7.6-44.9 months), 11 patients were alive without disease and 1 was alive with disease. One pregnancy was achieved postoperatively. CONCLUSION: Laparoscopic fertility-sparing surgery may represent a feasible option in well-selected patients with ovarian growing teratoma syndrome. Surgery should be performed in gynecologic oncology centers by experienced staff trained in endoscopic procedures. More research and long-time follow-up are needed to determine the oncological outcomes and safety of laparoscopic surgery in this population.

Exploring Uterine Involvement in Hysterectomy Samples Following Conization for Adenocarcinoma In Situ of the Uterine Cervix: Insights from a Multicenter Study by the FRANCOGYN Group.

BACKGROUND: Adenocarcinoma in situ (AIS) of the cervix can progress to invasive adenocarcinoma. While hysterectomy is standard, conservative management may be considered for women desiring future pregnancies. This study aimed to determine the prevalence of residual disease in hysterectomy specimens following excisional therapy with clear margins for AIS. METHODS: A retrospective FRANCOGYN cohort study was conducted on patients who underwent a hysterectomy after conization with clear margins for AIS between 2008 and 2021. The primary goal was to assess the prevalence of residual disease in the hysterectomy specimens. Secondary objectives included identifying preoperative predictors of residual disease and comparing recurrence rates between patients with and without residual disease. RESULTS: Of 53 hysterectomies performed after conization with negative margins for AIS, 20.8% (11/53) showed residual disease in the final histology. None of the patients had invasive cancer. In the residual disease group, 18% (2/11) had persistent CIN 3, and 82% (9/11) had persistent AIS. These patients tended to have higher BMI (27.5 kg/m² vs. 23.6 kg/m², p=0.04) and shorter endocervical margins (2mm vs. 5mm, p=0.01). No recurrences were observed during follow-up. CONCLUSION: Despite clear margins on the initial conization for AIS, 20% of patients had residual disease in their hysterectomy samples, though no invasive cancer was found. A hysterectomy should be considered after completing childbearing, even if initial margins are clear.

Spontaneous pregnancy after fertility-sparing surgery and adjuvant chemotherapy for advanced pure dysgerminoma: A case report.

Key Clinical Message: Fertility-sparing surgery and appropriate adjuvant chemotherapy for advanced malignant ovarian germ cell tumors have excellent survival results and promising reproductive and obstetric outcomes. Abstract: This case report aims to demonstrate the potential feasibility and success of fertility-sparing surgery (FSS) coupled with adjuvant chemotherapy in treating advanced malignant ovarian germ cell tumor (MOGCT), focusing on pure dysgerminoma, fertility, and achieving spontaneous pregnancy. The patient was a 23-year-old female who initially presented with complaints of abdominal distension and a palpable mass and was subsequently diagnosed with advanced MOGCT. The patient provided a complete clinical and radiological response to FSS with complete surgical staging and cisplatin-based chemotherapy (bleomycin, etoposide, and cisplatin). Despite being diagnosed with advanced MOGCT and treated with FSS and adjuvant chemotherapy, she later experienced spontaneous pregnancy, giving birth to a healthy child. This case study demonstrated the potential for successful fertility preservation and pregnancy in advanced-stage MOGCT patients treated with personalized treatment approaches. Nevertheless, a broader investigation is needed to understand the relevant complex dynamics and to ascertain whether FSS with adjuvant chemotherapy could be a reliable approach in treating advanced MOGCT.

Laparoscopic nephron-sparing surgery for complex renal cystic lesions: a single-center experience.

Objectives: This study aimed to explore the feasibility and safety of laparoscopic nephron-sparing surgery (LNSS) for complex renal cystic lesions. Methods: A retrospective study was conducted on 83 cases of complex renal cystic lesions treated with LNSS in our hospital. There were 32 men and 51 women, ranging in age from 24 to 73 years (average, 47.22 ± 9.03 years). The diameter of the cysts was 1.5-5.9 cm (average, 3.44 ± 0.86cm). According to the Bosniak classification, there were 15 cases of type II, 23 cases of type IIF, 29 cases of type III, and 16 cases of type IV complex renal cystic lesions. According to clinical classification based on the difficulty of laparoscopic partial nephrectomy and the depth of the lesion, the 83 complex renal cystic lesions were divided into 48 cases of the extra-renal type, 15 cases of the centrally located type, seven cases of the renal sinus type, and 13 cases of the renal hilum type. Results: Laparoscopic partial nephrectomy was successful in all 83 patients. The surgical time was 35-102 min (average, 52.13 ± 14.38 min), the intraoperative bleeding volume was 10-200 ml (average, 27.25 ± 12.26 ml), and the renal artery occlusion time was 12-28 min (average, 12.46 ± 4.45 min). There was no significant change in creatinine before and after surgery. The postoperative pathological results showed 71 cases of renal clear cell carcinoma, five cases of low malignant potential multilocular cystic renal tumors, and seven cases of pure renal cysts with all margins negative. Conclusions: There is potential for the malignant transformation of complex renal cysts into renal cell carcinoma. For complex renal cysts classified as Bosniak IIF or higher, surgical intervention is recommended, and LNSS is safe and effective. The complexity of the surgical procedure varies depending on the location classification of the complex renal cysts.

A Video-illustrated Overview of Reconstructive Surgical Techniques Following Penile Cancer Treatment.

Surgery is the cornerstone of treatment for penile squamous cell carcinoma. Following surgical excision, reconstructive surgery is beneficial to restore aesthetics, functionality, and overall quality of life of these patients. In this mini-review, we discuss the use of skin grafts, perineal urethrostomy, phalloplasty, and vascularised flaps as reconstructive options following penile cancer treatment. Illustrated by videos, we highlight the surgical approach, indications, complications, and outcomes of these reconstructive strategies. PATIENT SUMMARY: Reconstructive surgery is important to restore appearance, urinary function, and sexual function in patients who have been treated for penile cancer. We discuss the benefits and potential complications of various surgical reconstructive options, which are illustrated with videos.

Complications and Risk Factors in Patients with Soft Tissue Sarcoma of the Extremities Treated with Radiotherapy.

INTRODUCTION: Soft tissue sarcomas of the extremities (ESTSs) pose significant challenges in treatment and management due to their diverse nature and potential complications. This study aimed to assess complications associated with multimodal treatments involving surgery and radiotherapy (RT) and to identify potential risk factors. METHODS: We retrospectively analyzed nonmetastatic ESTS patients treated with surgery and pre- or post-operative RT between 2007 and 2020 in Strasbourg, France. Complications, including wound complications (WCs), lymphedema, acute and chronic RT-related complications, and fractures, were meticulously evaluated. RESULTS: A total of 169 patients diagnosed with localized ESTSs were included, with a median age of 64 years (range 21-94 years). ESTSs primarily occurred proximally (74.6%) and in the lower limbs (71%). The median follow-up was 5.5 years. WCs occurred in 22.5% of patients, with proximal and lower extremity tumors being significant risk factors. Acute RT-related complications included radiodermatitis, with grade ≥ 2 occurring in 43.1% of patients, which was associated with superficial tumors. Three patients had an edema grade ≥ 2. Chronic complications included telangiectasias (21.7%) and fibrosis (38.7%), with higher rates associated with larger PTVs and higher RT doses, respectively. Fractures occurred in 5 patients, mainly in the tibia (40%). CONCLUSIONS: Multimodal treatment of ESTSs demonstrated excellent tolerance, with manageable side effects. Numerous risk factors have been highlighted, providing insights for optimizing treatment strategies and enhancing patient care in this rare disease.

Oncological outcomes of fertility-sparing surgery versus radical surgery in stage - epithelial ovarian cancer: a systematic review and meta-analysis.

BACKGROUND: The oncological outcomes of fertility-sparing surgery (FSS) compared to radical surgery (RS) in patients with stage I epithelial ovarian cancer (EOC) remain a subject of debate. We evaluated the risk ratios (RRs) for outcomes in patients with stage I EOC who underwent FSS versus RS. METHODS: We conducted a systematic search of PubMed, Web of Science, and Embase for articles published up to November 29, 2023. Studies that did not involve surgical procedures or included pregnant patients were excluded. We calculated the RRs for disease-free survival, overall survival, and recurrence rate. The quality of the included studies was assessed using the Cochrane Risk of Bias in Nonrandomized Studies of Interventions (ROBINS-I) tool. The meta-analysis was registered on PROSPERO (CRD42024546460). RESULTS: From the 5,529 potentially relevant articles, we identified 83 articles for initial screening and included 12 articles in the final meta-analysis, encompassing 2,906 patients with epithelial ovarian cancer. There were no significant differences between the two groups in disease-free survival (RR [95% confidence interval {CI}], 0.90 [0.51, 1.58]; P = 0.71), overall survival (RR [95% CI], 0.74 [0.53, 1.03]; P = 0.07), and recurrence rate (RR [95% CI], 1.10 [0.69, 1.76]; P = 0.68). In sensitivity analyses, the significant difference was observed only for overall survival (before exclusion: RR [95% CI], 0.74 [0.53-1.03], P = 0.07; after exclusion: RR [95% CI], 0.70 [0.50-0.99]; P = 0.04). CONCLUSIONS: This is the first and only individual patient data meta-analysis comparing disease-free survival, overall survival, and recurrence rate of patients with early-stage epithelial ovarian cancer undergoing FSS and RS. FSS was associated with similar disease-free survival and risk of recurrence as RS. We hypothesized that the decreased overall survival in the FSS group could not be attributed to distant metastases from epithelial ovarian cancer.
