Embryological Development and Topographic Anatomy of Pelvic Compartments-Surgical Relevance for Pelvic Lymphonodectomy

Background The oncological outcome of surgery for the treatment of pelvic malignancies can be improved by performing pelvic lymphonodectomy. However, the extent and regions of lymph node harvest are debated and require profound knowledge of anatomy in order to avoid collateral damage. Methods The embryological development and topographic anatomy of pelvic compartments in relation to pelvic lymphonodectomy for rectal, uterine, and prostate cancer are reviewed. Based on pre-dissected anatomical specimens, lymph node regions and drainage routes of the posterior and urogenital pelvic compartments are described in both genders. Anatomical landmarks are highlighted to identify structures at risk of injury during pelvic lymphonodectomy. Results The ontogenesis of urogenital and anorectal compartments and their lymphatic supply are key factors for adequate lymphonodectomy, and have led to compartment-based surgical resection strategies. However, pelvic lymphonodectomy bears the risk of injury to somatic and autonomic nerves, vessels, and organs, depending on the regions and extent of surgery. Conclusion Embryologically defined, compartment-based resection of pelvic malignancies and their lymphatic drainage routes are based on clearly delineated anatomical landmarks, which permit template-oriented pelvic lymphonodectomy. Comprehensive knowledge of pelvic anatomy, the exchange of surgical concepts between specialties, and minimally invasive techniques will optimize pelvic lymphonodectomy and reduce complications

Pre- and intratherapeutic predictors of overall survival in patients with advanced metastasized castration-resistant prostate cancer receiving Lu-177-PSMA-617 radioligand therapy

Background Systemic Lutetium-177 prostate-specific membrane antigen-617 radioligand therapy (Lu-177-PSMA-617-RLT) is a novel treatment approach in patients suffering from metastasized castration-resistant prostate cancer. Nonetheless, a therapeutic response may fail to appear in a proportion of patients. This study aims to identify routinely obtainable pre- and intratherapeutic parameters to allow a prediction of overall survival in patients receiving Lu-177-PSMA-617 radioligand therapy. Methods Between January 2015 and December 2020 52 patients treated with a total of 146 cycles Lu-177-PSMA-617-RLT were retrospectively analysed in a single-center trial. The median overall survival time (OS) was compared to pre-therapeutic serological parameters, the extend of metastatic spread and previously performed therapies using Kaplan-Meier estimators and multivariate Cox-regression. Bonferroni-Holm correction was performed on all statistical tests. Results The median OS of all patients was 55.6 weeks. Multivariate Cox-regression revealed significant lower survival for decreased pretherapeutic hemoglobin levels (HR 0.698 per g/dl; 95%-CI 0.560-0.872; p = 0.001), increased lactate dehydrogenase (LDH) levels (HR 1.073 per 25 U/l; 95%-CI 1.024-1.125; p = 0.003) and the presence of hepatic metastasis (HR 6.981; 95%-CI 2.583-18.863; p < 0.001). Increased pretherapeutic c-reactive protein (CRP), alkaline phosphatase (ALP) and gamma-glutamyltransferase (GGT) levels were also associated with a shorter survival. Conclusion Pre-therapeutic hemoglobin and LDH levels, as well as the presence of hepatic metastasis are independent predictors of overall survival in patients receiving Lu-177-PSMA-617-RLT. CRP, ALP and GGT levels cloud be utilized as additional decision aids when a Lu-177-PSMA-617-RLT is intended. Trial Registration Not applicable (retrospective observational study)

clinical recommendations from the european society for sexual medicine exploring partner expectations satisfaction in male and phalloplasty cohorts the impact of penile length girth and implant type reservoir placement and the influence of comorbidities and social circumstances

Abstract Introduction To date, several aspects of inflatable penile prosthesis (IPP) surgical procedure have been poorly studied. Aim The aim of this study was to review the evidence associated with IPP implantation and provide clinical recommendations on behalf of the European Society for Sexual Medicine (ESSM). Overall, 130 peer-reviewed studies and systematic reviews, which were published from 2007−2018 in the English language, were included. Methods MEDLINE and EMBASE were searched for randomized clinical trials, meta-analyses, and open-label prospective and retrospective studies. Main Outcome Measure The panel provided statements exploring patients and partner expectations, satisfaction in male and phalloplasty cohorts, the impact of penile length, girth and implant type, reservoir placement, the influence of comorbidities, and social circumstances. Levels of evidence were provided according to the Oxford 2011 criteria and graded as for the Oxford Centre for Evidence-Based Medicine recommendations. Results In the preoperative setting, it is fundamental to identify and interact with difficult patients with the intention of enhancing the surgeon's ability to establish the surgeon-patient relationship, reduce physical and legal risk, as well as enhancing patient satisfaction. To address this need, the mnemonic Compulsive, Unrealistic, Revision, Surgeon Shopping, Entitled, Denial, and Psychiatric ("CURSED") has been suggested to identify patients who are at high risk of dissatisfaction. The current recommendations suggest improving glycemic control in patients with diabetes. Available evidence suggests evaluating transplant recipients with the criteria of Barry, consisting of stable graft function for >6 months, avoidance of intra-abdominal reservoir placement, and low-dose immunosuppression. HIV status does not represent a contraindication for surgery. Smoking, peripheral vascular disease, and hypertension may be associated with an increased risk of revision surgery. Patients with spinal cord injury may receive IPP. Patients aged ≥70 years, as well as obese patients, can be offered IPP. The IPP implantation can be performed in patients with stable Peyronie's disease. Ectopic high submuscular reservoir placement can be considered as an alternative method. Clinical Implications There is a relevant lack of high-level data and definite conclusions in certain areas remain difficult to draw. Strength & Limitations All studies have been evaluated by a panel of experts providing recommendations for clinical practice. Because of lack of sufficient prospective data, some of the included studies are retrospective and this could be stated as a limitation. Conclusion This ESSM position statement provides recommendations on optimization of patient outcome by patient selection, and individualized peri- and intra-operative management. ESSM encourages centers to collaborate and to create prospective, multicenter registries in order to address this topic of increasing importance. Osmonov D, Christopher AN, Blecher GA, et al.

Laparoscopic varicocelectomy in male infertility

Background!#!The suitability of laparoscopic varicocelectomy for assisted reproductive technology depends on the improvement of semen parameters. The present study analyzed the improvement of semen parameters following laparoscopic varicocele ligation.!##!Material and methods!#!A retrospective study of the laparoscopic varicocele clippings at the Department of Urology of University Hospital of Kiel between the years 2007 and 2019 was conducted. The semen analyses according to WHO standards (sperm count, density, motility and morphology) were conducted before and 12 months after surgery. Screening for surgical complications took place at the time of the follow-up seminal analysis. Included were patients with oligozoospermia, asthenozoospermia and/or teratozoospermia (group 1, OAT) or with nonobstructive azoospermia (group 2, NOA).!##!Results!#!This study included data of 27 patients and 22 patients presented preoperative OAT (81%, group 1). Another 5 patients showed NOA (19%, group 2). Data of group 1 showed that semen parameters normalized in 32% of the patients after surgery. Significant improvement in total sperm count (p &amp;lt; 0.005), sperm density (p &amp;lt; 0.005) and total motile sperm count (p &amp;lt; 0.005) was observed. No deterioration of semen parameters was observed. In group 2 we detected spermatozoa in 1 case in the postoperative ejaculate. None of the patients showed complications according to the Clavien-Dindo classification, postoperative hydrocele formation or recurrence of varicocele at the time of control spermiogram.!##!Conclusion!#!Laparoscopic varicocelectomy is a valid therapeutic approach to improve semen parameters for further assisted reproductive techniques. Spermatogenesis may be induced for patients with NOA. Normalization of semen parameters can be achieved for patients with OAT

Preputioplasty as a surgical alternative in treatment of phimosis

Preputioplasty denotes various surgical techniques directed at resolving phimosis without the need for radical or partial circumcision. This narrative review summarizes the best-known surgical techniques of preputioplasty. A MEDLINE and EMBASE-based literature search of original manuscripts and case reports published in English has been carried out using the following key words: 'circumcision', 'partial circumcision', 'phimosis', 'paraphimosis', and 'preputioplasty'. Six different procedures are explored in more detail and illustrated. The complication rates of all surgical procedures presented here are reported to be low. In cases of medical (rather than cultural and religious) indications, foreskin-preserving procedures present useful alternatives to circumcision in the routine clinical practice of urologists and pediatric surgeons

Extended Salvage Pelvic Lymph Node Dissection in Patients with Recurrent Prostate Cancer

Background. Treatment of patients with a biochemical recurrence (BCR) of prostate cancer (PCa) is generally difficult and without valid treatment options. Since 2004 we have been developing therapeutic possibilities for these patients. Methods. We retrospectively analyzed a cohort of 41 patients with a BCR of PCa and a mean followup of 40.3±20.8 months. Group 1 (n=10): salvage radical prostatectomy (sRP) with SePLND (salvage extended pelvic lymph nodes dissection) (initial treatment: combined brachytherapy). Group 2 (n=22): SePLND (initial treatment: radical prostatectomy (RP)). Group 3 (n=9): SePLND (initial treatment: RP and adjuvant radiation therapy (RT)). We observed PSA, PSA-velocity, localization of LNs and LNs+, BCR-free period, and BR (biochemical response). Results. Group 1: 60% with BCR-freedom (mean 27.2 months). Group 2: 63.6% with BCR-freedom (mean 17.5 months). Group 3: 33.3% with BCR-freedom (mean 17.6 months). In total, BCR-freedom was observed in 23 of 41 patients (56.1%) after salvage surgery. 75.6% of all patients showed a BR. 765 LNs were removed and 14.8% of these were LN+. Conclusions. The BCR-free period and BR are comparable in all three groups. Sensibility to ADT can be reestablished and prolonged as a result of SePLND. Multicenter studies are needed for a reliable output
