Value of prolonged scrotal drainage after penile prosthesis implantation: a multicenter prospective nonrandomized pilot study.

We aimed to understand the risks and benefits of post-inflatable penile prosthesis (IPP) implantation drainage and optimal duration. Our patients were divided into 3 groups: Group 1 (n = 114) had no drain placed, Group 2 had a drain placed for 24 h (n = 114) and Group 3 had a drain placed for 72 h (n = 117). Postoperative scrotal hematoma and prosthesis infection rates were compared between the groups. The patients from Group 3 demonstrated a statistically significant lower incidence of hematoma on the 10th postoperative day: (n = 1, 0.9%) compared to Group 2: (n = 11, 9.6%) and Group 1: (n = 8, 7%), (p = 0.013). However, on the 3rd postoperative day, there was a statistically significant lower incidence of hematoma in both Groups 3 and 2: (0.9% and 6.1%, respectively) vs. Group 1: (11.4%), (p = 0.004). Hematoma rates followed the same group order after the first day of surgery: 1.7% (n = 2), 5.3% (n = 6), and 8.8% (n = 10), respectively, (p = 0.05). Five patients (4.4%) in Group 1 and four patients (3.5%) in Group 2 developed an IPP associated infection, opposed to only a single patient (0.85%) in Group 3, (p = 0.210). We concluded that prolonged scrotal drainage for 72 h after virgin IPP implantation significantly reduces hematoma and infection rates.

[Quality of life in patients who suffered erectile dysfunction and underwent penile implant surgery in terms of sexual satisfaction of the patient and partner]. / Lebensqualität von Patienten mit hydraulischen penilen Implantaten bei erektiler Dysfunktion in Bezug auf die sexuelle Zufriedenheit des Patienten und seinem/seiner Partner/Partnerin.

BACKGROUND: Erectile dysfunction is a condition that shows a continuously growing prevalence in the male population. The penis prosthesis implant (PPI) qualifies as an effective form of therapy. OBJECTIVES: The aim of this study was to analyze the sexual satisfaction rate and quality of life in patients who had suffered from erectile dysfunction and who were treated with a penile prosthesis. The patient's partners were also surveyed. METHODS: We collected data from patients who underwent surgery in the Center of Excellence for Penile Implants, University Hospital Schleswig-Holstein, Campus Kiel, Kiel, Germany. Questionnaires with validated scores (EDITS, EDITS Partner) were sent to all patients and their partners via mail. RESULTS: The satisfaction rate in this study was high which shows that the patients and partners are pleased, and the high sexual satisfaction rate led to a higher quality of life. CONCLUSION: The penile prosthesis implantation as a last option of therapy for erectile dysfunction is useful and brings more than adequate results.

[Multicenter comparison of complications after robot-assisted and open simple prostatectomy]. / Multizentrischer Vergleich von Komplikationen nach roboterassistierter und offen chirurgischer Prostataadenomenukleation.

INTRODUCTION: Robot-assisted simple prostatectomy (RASP) is a relatively new minimally invasive procedure for surgical treatment to manage symptomatic, therapy-refractory benign prostate hyperplasia (BPH) in prostate volumes >80 cm3. Thus, postoperative morbidity based on Clavien-Dindo and hematological parameters in RASP and open simple prostatectomy (OSP) procedures are examined. PATIENTS AND METHODS: We retrospectively reviewed a total of 78 patients: 39 patients underwent RAPS and 39 OSP. The following parameters were statistically evaluated and compared: age, PSA value, prostate volume, ASA score, duration of hospital stay, operative time, Hb decrease on postoperative (po) day 1 and in the 5 five po days, CRP peak in the first 5 po days and transfusion rate. RESULTS: The comparison between RASP and standard OSP showed no significant differences regarding the mean patient age (73 vs. 74 years; p =0.54), PSA values (7.7 vs. 10.7 ng/ml; p =0.17), ASA score (2.2 vs. 2.3; p =0.26) and prostate volume (130 vs. 113 cm3; p =0.07). Patients in the RAPAE group had statistically significant longer surgery (178 vs. 110 min; p =<0.01) with a significantly smaller decrease in Hb on po day 1 (1.9 vs. 3.3 g/dl; p ≤0.01) and in the first 5 po days (2.4 vs. 4.2 g/dl; p ≤0.01), lower need for preserved blood (3% vs. 26%; p =0.01) and number of blood bags (0.1 vs. 1.3; p =0.01), a lower po Clavien-Dindo score (0.44 vs. 1.23; p =0.003) and lower CRP values (52 vs. 104 mg/l; p ≤0.01) in the first 5 po days. CONCLUSION: RASP is a safe procedure that offers the advantage of reduced blood loss and blood bag consumption and rare complications due to the minimally invasive surgical method. The OSP group showed an increased occurrence of complications due to bleeding, leading to prolonged hospitalization and significantly increased need for blood transfusion. The lesser increase of CRP in RASP group is a result of the lower invasiveness of the robot-assisted procedure.

High-submuscular vs. space of Retzius reservoir placement during implantation of inflatable penile implants.

We have evaluated the data of patients who underwent ectopic high submuscular reservoir placement during implantation of inflatable penile prostheses and compared them to those of patients who underwent to traditional reservoir placement in the space of Retzius (SR). The main focus was on evaluating complications and patient satisfaction rates in both methods of RP. One hundred and forty-two patients underwent implantation of the Coloplast Titan OTR prosthesis with exclusive use of the "Clover Leaf" reservoir. We performed a retrospective evaluation, analyzing the treatment-associated complications by means of the Clavien-Dindo classification. All patients as well as their partners received questionnaires with validated scores. Group I: 70 (49.3%) patients who underwent HSM RP. Group II: 72 (50.7%) patients who underwent SR RP. Neither grade IV nor grade V Clavien-Dindo complications were documented. In total, we observed 4 (3.3%) cases grade III b complications, which resulted in revision. Distribution was as follows: infected device (n = 4), scrotal hematoma (n = 2), scrotal seroma (n = 1), and scrotal skin fistula (n = 1). 88% of the patients with ectopic HSM RP and 81% with traditional SR RP were satisfied with their implant. Of the patients with HSM RP, 64.3% (n = 45; BMI range: 18.5-28.8) reported that they were able to feel their reservoir by palpation immediately after surgery. Palpability disappeared in 80% of the patients in this group (BMI > 26.5) after capsule formation at 3 months post-surgery. Only one patient (1.4%; BMI 20.5) reported that he was able to see the reservoir. Our findings suggest that the novel reservoir placement is safe, efficient and results in excellent patient satisfaction, even if the reservoir is initially palpable or visible.

[Epidemiology of penile cancer]. / Epidemiologie des Peniskarzinoms.

BACKGROUND: Penile cancer represents a rarity in daily clinical practice. OBJECTIVES: The aim is to identify global differences concerning the incidence, social and risk factors. METHODS: The past and current epidemiologic literature is analyzed concerning incidence rates and risk factors. The latter are discussed concerning their potential with regard to disease prevention. RESULTS: Globally, incidence rates of penile cancer range from low to nonexistent. Distinct differences are found when comparing industrialized countries with emerging and developing countries. Phimosis seems to be a crucial risk factor in the formation of penile cancer. Additionally, chronic inflammatory diseases of the penis were found to be associated with a higher risk. CONCLUSIONS: Preventive measures should be considered in relation to the rarity of the disease, especially in the valuation of circumcision during early childhood. Regular clinical examination of the penis is a sensible measure of early detection.

Application of ultrasound imaging biomarkers (HistoScanning™) improves staging reliability of prostate biopsies.

OBJECTIVE: Imaging biomarkers like HistoScanning™ augment the informative value of ultrasound. Analogue image-guidance might improve the diagnostic accuracy of prostate biopsies and reduce misclassifications in preoperative staging and grading. RESULTS: Comparison of 77 image-guided versus 88 systematic prostate biopsies revealed that incorrect staging and Gleason misclassification occurs less frequently in image-guided than in systematic prostate biopsies. Systematic prostate biopsies (4-36 cores, median 12 cores) tended to detect predominantly unilateral tumors (39% sensitivity, 90.9% specificity, 17.5% negative and 50% positive predictive values). Bilateral tumors were diagnosed more frequently by image-guided prostate biopsies (87.9% sensitivity, 72.7% specificity, 50% negative and 96.8% positive predictive values). Regarding the detection of lesions with high Gleason scores ≥ 3 + 4, systematic prostate and image-guided biopsies yielded sensitivity and specificity rates of 66.7% vs 93.5%, 86% vs 64.5%, as well as negative and positive predictive values of 71.2% vs 87%, and 83.3% vs 79.6%, respectively. Potential reason for systematic prostate biopsies missing the correct laterality and the correct Gleason score was a mismatch between the biopsy template and the respective pathological cancer localization. This supports the need for improved detection techniques such as ultrasound imaging biomarkers and image-adapted biopsies.

[Significance and Importance of Pelvic Lymphadenectomy in Low-Risk Prostate Cancer Patients]. / Bedeutung und Notwendigkeit der pelvinen Lymphadenektomie bei Low-Risk Prostatakarzinompatienten.

BACKGROUND: The most frequent carcinoma in male patients is prostate cancer. D'Amico and colleagues (1998) set up a classification to assess the aggressiveness of prostate cancer growth and the risk of metastatic spread, taking into account the following parameters: PSA, Gleason Score (GS), and tumour spread (T). The combination of these parameters results in a classification of low-, intermediate- and high-risk patients.In the context of a larger heuristic study entitled "Low-Risk Prostate Cancer Patients: Significance And Importance Of Pelvic Lymphadenectomy in Localized Prostate Carcinomas", we observed the correlation of the parameters PSA, GS and T stage with the occurrence of lymph node metastases in low-risk-patients who underwent lymphadenectomy during radical prostatectomy. PATIENTS/MATERIALS AND METHODS: Due to a lack of evidence - none of the confirmed LR (low-risk=LR) patients was diagnosed with metastases - we set up a subclassification for LR patients for the following corridor transition zone between low-risk and high-risk patients (based on the D'Amico classification):PSA≤10 ng/ml and GS≤7a (c: 7a) and clinical stage T1a-T2c (c: T2b, T2c): The population consists of 288 prostate cancer patients (60 low-risk (LR) patients, 228 corridor (c) patients). We analysed the number and frequency of removed lymph nodes and lymph node metastases. Moreover, we analysed the population with a view to a postoperative GS upgrade. The results are based on heuristic methods. RESULTS: The situation regarding the data in the transition zone, i. e. in the corridor area, and in the verified low-risk range is very complicated:In total, 3 743 lymph nodes were removed in 288 patients (mean: 13 lymph nodes). Of these only 7 lymph nodes in 5 patients from the corridor group were metastatic. The overall number of removed lymph nodes in these 5 patients lies within a small interval [23,32]; 26 lymph nodes were removed on average. A postoperative Gleason Score upgrade was found in 20.14% of the whole patient population. CONCLUSION: A postoperative Gleason Score upgrade in every fifth patient shows a highly relevant preoperative undergrading in these patients, which may lead to inadequate treatment. An opening of the D'Amico classification to include a corridor category of patients could be an opportunity to minimise preoperative undergrading. In this context, pelvic lymphadenectomy must be considered, at least for corridor patients.

[Robot-assisted Pylorus-Preserving Partial Pancreaticoduodenectomy (Kausch-Whipple Procedure)]. / Roboterassistierte, pyloruserhaltende partielle Duodenopankreatektomie nach Kausch-Whipple.

BACKGROUND: The surgical treatment of pancreatic head tumours is one of the most complex procedures in general surgery. In contrast to colorectal surgery, minimally-invasive techniques are not very commonly applied in pancreatic surgery. Both the delicate dissection along peri- and retropancreatic vessels and the extrahepatic bile ducts and subsequent reconstruction are very demanding with rigid standard laparoscopic instruments. The 4-arm robotic surgery system with angled instruments, unidirectional movement of instruments with adjustable transmission, tremor elimination and a stable, surgeon-controlled 3D-HD view is a promising platform to overcome the limitations of standard laparoscopic surgery regarding precise dissection and reconstruction in pancreatic surgery. INDICATION: Pancreatic head resection for mixed-type IPMN of the pancreatic head. PROCEDURE: Robot-assisted, minimally-invasive pylorus-preserving pancreaticoduodenectomy (Kausch-Whipple procedure). CONCLUSION: The robotic approach is particularly suited for complex procedures such as pylorus-preserving pancreatic head resections. The fully robotic Kausch-Whipple procedure is technically feasible and safe. The advantages of the robotic system are apparent in the delicate dissection near vascular structures, in lymph node dissection, the precise dissection of the uncinate process and, especially, bile duct and pancreatic anastomosis.

[Salvage lymphadenectomy in patients with prostate cancer recurrence: A review]. / Salvagelymphadenektomie beim Rezidiv eines Prostatakarzinoms : Eine Übersicht.

BACKGROUND: Salvage extended pelvic lymph node dissection (salvage ePLND) in patients with prostate cancer (PCa) biochemical recurrence is an alternative to the commonly used androgen deprivation therapy (ADT) and/or chemotherapy. Small patient number, insufficient accuracy of contemporary imaging methods for lymph node relapse diagnostics, and the lack of prospective data present limiting factors for a wider application of salvage ePLND. The purpose of this publication is to review German and European data and studies on the subject of salvage ePLND and to discuss future perspectives. MATERIALS AND METHODS: We analyzed available studies up to October 2014 from Medline with the keywords "salvage lymph node dissection prostate cancer". RESULTS: A total of 51 publications since 1984 (up to October 2014) meeting the search criteria were found. Ten of these were studies that analyzed the results of salvage ePLND. Of these 10 studies, 6 originated from German clinics. Furthermore, among these 51 publications, there were 2 clinical case reports (1 from Germany) and 3 reviews (none from Germany). CONCLUSIONS: The available data show insufficient evidence-based validity. There have been no prospective studies and just one multicenter study. However, single-center retrospective studies have shown promising results. Salvage ePLND leads to biochemical remission, freedom from clinical recurrence, and probably also to renewed response to ADT in patients with castration-resistant PCa. Multicenter prospective studies should be conducted in Germany (where most of the available studies have been performed). The selection of patients should be analyzed in order to identify clear selection criteria for salvage ePLND.

[Interdisciplinary Diagnosis and Treatment of Deep Infiltrating Endometriosis]. / Interdisziplinäre Diagnostik und Therapie der tief infiltrierenden Endometriose.

Endometriosis is the second most common benign female genital disease after uterine myoma. This review discusses the interdisciplinary approach to the treatment of deep infiltrating endometriosis. Endometriosis has been defined as the presence of endometrial glands and stroma outside the internal epithelial lining of the cavum uteri. As a consequence, endometriosis can cause a wide range of symptoms such as chronic pelvic pain, subfertility, dysmenorrhea, deep dyspareunia, cyclical bowel or bladder symptoms (e.g., dyschezia, bloating, constipation, rectal bleeding, diarrhoea and hematuria), abnormal menstrual bleeding, chronic fatigue or low back pain. Approx. 50 % of teenagers and up to 32 % of women of reproductive age, operated for chronic pelvic pain or dysmenorrhoea, suffer from endometriosis. The time interval between the first unspecific symptoms and the medical diagnosis of endometriosis is about 7 years. This is caused not only by the non-specific nature of the symptoms but also by the frequent lack of awareness on the part of the cooperating disciplines with which the patients have first contact. As the pathogenesis of endometriosis is not clearly understood, a causal treatment is still impossible. Treatment options include expectant management, analgesia, hormonal medical therapy, surgical intervention and the combination of medical treatment before and/or after surgery. The correct treatment for each patient should take into account the severity of the disease and whether the patient desires to have children. The treatment should be as radical as necessary and as minimal as possible. The recurrence rate among treated patients lies between 5 and > 60 % and is very much dependent on the integrated management and surgical skills of the respective hospital. Consequently, to optimise the individual patient's treatment, a high degree of interdisciplinary cooperation in diagnosis and treatment is crucial and should, especially in the case of deep infiltrating endometriosis, be undertaken in appropriate centres.

[Long-term results of sentinel node biopsy diagnostics in penile carcinoma : Dynamic sentinel node biopsy in cases with nonpalpable lymph nodes in the groin]. / Langzeitergebnisse der Sentinel-Lymphknotendiagnostik beim Peniskarzinom : Dynamische Sentinel-Lymphknotenbiopsie bei nicht-palpablen Leistenlymphknoten.

OBJECTIVE: Dynamic sentinel node biopsy (DSNB) has been recommended in the EAU guidelines for several years as a minimally invasive method for lymph node staging in patients with penile carcinoma and nonpalpable lymph nodes. However, due to the high methodological demands and the primarily unreliable results, this method is rarely used in Germany. The aim of this study was to establish the reliability and morbidity of this method. MATERIAL AND METHODS: The frequency of lymph node recurrent disease and complications were prospectively recorded in patients with initially nonpalpable inguinal lymph nodes and histologically negative sentinel lymph nodes. Quality criteria were the false negative rate (percentage of lymph node recurrence in negative procedures) and the morbidity rate. Inguinal regions with palpable lymph nodes and/or evidence of metastases were not considered. RESULTS: The study included 37 patients with histologically negative sentinel lymph nodes in 63 groins with nonpalpable inguinal lymph nodes. There were 21 T1(a/b) stages, 10 T2, and 6 T3 stages. Tumor differentiation was good in 4, moderate in 26, and poor in 7 patients. During a median follow-up of 52 months (range 1-131 months), we observed a bilateral lymph node recurrence in 1 patient and a conservatively managed prolonged lymphorrhea in another patient. Per inguinal region the false-negative rate was 3.2 % and the morbidity rate was 1.6 %; seen per patient the rates were both 2.7 %. CONCLUSIONS: DSNB is a reliable method of lymph node staging in patients with penile carcinoma and nonpalpable inguinal lymph nodes. The high degree of reliability in combination with the low morbidity justifies the higher methodical complexity of this method.

Computer-aided transrectal ultrasound: does prostate HistoScanning™ improve detection performance of prostate cancer in repeat biopsies?

BACKGROUND: An imaging tool providing reliable prostate cancer (PCa) detection and localization is necessary to improve common diagnostic pathway with ultrasound targeted biopsies. To determine the performance of transrectal ultrasound (TRUS) augmented by prostate HistoScanning(TM) analysis (PHS) we investigated the detection of prostate cancer (PCa) foci in repeat prostate biopsies (Bx). METHODS: 97 men with a mean age of 66.2 (44-82) years underwent PHS augmented TRUS analysis prior to a repeat Bx. Three PHS positive foci were defined in accordance with 6 bilateral prostatic sectors. Targeted Bx (tBx) limited to PHS positive foci and a systematic 14-core backup Bx (sBx) were taken. Results were correlated to biopsy outcome. Sensitivity, specificity, predictive accuracy, negative predictive value (NPV) and positive predictive value (PPV) were calculated. RESULTS: PCa was found in 31 of 97 (32%) patients. Detection rate in tBx was significantly higher (p < .001). Detection rate in tBx and sBx did not differ on patient level (p ≥ 0.7). PHS sensitivity, specificity, predictive accuracy, PPV and NPV were 45%, 83%, 80%, 19% and 95%, respectively. CONCLUSIONS: PHS augmented TRUS identifies abnormal prostatic tissue. Although sensitivity and PPV for PCa are low, PHS information facilitates Bx targeting to vulnerable foci and results in a higher cancer detection rate. PHS targeted Bx should be considered in patients at persistent risk of PCa.

[Urogynecology II: urinary incontinence in men and women: surgical treatment of urinary incontinence and prolapse]. / Urogynäkologie II: Harninkontinenz bei Mann und Frau : Chirurgische Therapie der Harninkontinenz und des Prolapses.

Numerous surgical procedures are available for the treatment of stress urinary incontinence in women and men. On a par with classical therapy options (e.g. colposuspension and artificial sphincter prosthesis) suburethral tape procedures have become established as the minimally invasive standard of care. Regarding comorbidities and recurrent urinary incontinence, therapeutic procedures should be modified on an individual basis. It is crucial to involve patients in therapeutic decision-making and counseling should be given with respect to all conservative and operative alternatives.

[Urinary incontinence in men and women. Diagnostics and conservative therapy]. / Harninkontinenz bei Frau und Mann. Diagnostik und Konservative Therapie.

Urinary incontinence can affect men and women to the same degree. A differentiation is made between stress incontinence (i.e. urine discharge as a result of physical activities, sneezing or coughing), urge incontinence (i.e. strong urge to void with involuntary discharge of urine), mixed urinary incontinence and special forms. While men and women share the pathophysiology of urge-associated urinary incontinence, the multifactorial female urinary stress incontinence is in contrast to the stress incontinence in men which is almost exclusively caused by prostatectomy (postprostatectomy). The basic diagnostic procedure for urinary incontinence is largely non-invasive. Special diagnostic procedures are reserved for recurrences and preparation for operative measures. Therapy is oriented to the degree of suffering and patient compliance and incorporates conservative measures as first line therapy (e.g. lifestyle changes, bladder and continence training). Duloxetin is approved for the medicinal therapy of female urinary stress incontinence. The treatment of urge-associated urinary incontinence is primarily with anticholinergic agents. Alternatively, procedures for neuromodulation, a beta mimetic or injection therapy with botulinum toxin can be used in the future.

[Robotic-assisted minimally invasive abdominothoracal oesophageal resection with intrathoracic anastomosis]. / Roboterassistierte, minimalinvasive abdominothorakale Ösophagusresektion mit intrathorakaler Anastomose.

BACKGROUND: Ivor Lewis oesophagectomy is one of the approaches used worldwide for treating oesophageal cancer. The adoption of minimally invasive oesophagectomy has increased worldwide since its first description more than 15 years ago. However, minimally invasive oesophagectomy with a chest anastomosis has advantages. By using a four-arm robotic platform, not only the preparation of the gastric tube and mobilisation of the oesophagus but also the intrathoracic anastomosis of the oesophagogastrostomy can be performed in a comfortable and safe way. INDICATION: The indication for oesophageal resection is oesophageal cancer. PROCEDURE: The operative procedure comprises robotic-assisted abdominothoracal oesophageal resection with reconstruction by a gastric tube and intrathoracic anastomosis (Ivor Lewis procedure). CONCLUSION: Robotic abdominal and thoracic minimally invasive esophagectomy is feasible, and safe with a complete lymph node dissection. Especially the intrathoracic anastomosis of the oesophagogastrostomy can be performed in a comfortable and safe way.

[A serious complication after bladder embolisation due to massive tissue necrosis in the gluteal region]. / Eine schwerwiegende Komplikation in Form massiver Gewebenekrosen in der glutealen Region nach Embolisation der Harnblase.

Adequate and successful treatment of Hb-relevant macrohaematuria in bladder cancer patients is a frequent problem in clinical routine. It is often not easy to identify a good treatment option for inoperable older patients. A possible option is transcatheter-based arterial embolisation of the vesical artery. Unfortunately there are only few publications about this procedure; a detailed analysis of bladder embolisation is difficult to find in the literature. Our report illustrates the embolisation of the vesical artery in an 84-year-old patient with bladder cancer with an Hb-relevant, transurethral non-curable macrohaematuria. Massive necrosis of the M. gluteus maximus developed after embolisation of the vesical artery. During the ensuing surgery, the entire musculature of the gluteal region was removed, and the N. ischiadicus was cut. The patient was supervised first in the intensive care and then in the palliative care ward. The patient's prognosis is unfavourable due to the localisation and size of the wound and consecutive life-long immobility. Embolisation of the vesical artery is a viable procedure, but only if alternative therapeutic strategies are impossible. It should only be performed by an experienced radiologist and it is strongly recommended not to apply liquid embolisation agents. Inadequate embolisation of the vesical artery can lead to extensive necrosis. Radiological diagnostics help to identify the margins of the necrotic region. During the intervention, maximum attention should be paid to saving the entirety of N. ischiadicus, especially in patients with large necrotic areas.

[Sentinel lymph node biopsy for penile carcinoma : Assessment of reliability]. / Sentinel-Lymphknotenbiopsie beim Peniskarzinom : Überprüfung der Zuverlässigkeit.

BACKGROUND: The European Association of Urologists recommends dynamic sentinel node biopsy (DSNB) as the first choice diagnostic approach for lymph node staging of non-palpable inguinal lymph nodes in penile carcinoma. The aim of this study was to assess the reliability of minimally invasive inguinal DSNB. MATERIAL AND METHODS: Between 2004 and 2012 DSNB was used in all patients with invasive penile carcinoma and non-palpable inguinal lymph nodes. For assessment of reliability the rate of false negative results was determined and complications were documented. The results were analyzed prospectively. RESULTS: In the study period DSNB was performed in a total of 29 patients and it was possible to prove lymph node metastasis in 2 patients with 1 patient who developed lymph node metastasis after a negative DSNB. Thus the false negative rate was 3.70 %. A morbidity rate of 3.45 % was also observed. CONCLUSION: Sentinel lymph node biopsy is a reliable diagnostic method. The sophisticated requirements both methodologically and logistically suggest that this procedure should only be performed in specialized centres.

[Extended salvage pelvic and retroperitoneal lymph node dissection due to prostate cancer relapse]. / Ausgedehnte Salvage-Lymphknotenentfernung aus Becken- und Retroperitoneum bei Prostatakarzinomrezidiv.

Treatment of a biochemical prostate cancer relapse represents a difficult clinical dilemma, which has remained without a definitive solution so far. Based on clinical studies, we combine radical prostatectomy with extended pelvic lymph node dissection in intermediate and high risk patients as a routine procedure at our clinic. In this paper, we report on a case of extended salvage lymphadenectomy performed due to biochemical prostate cancer recurrence. The 56-year-old patient came to our clinic in April 2012 with a finding of lymph node metastasis according to PET-CT imaging. Laparoscopic radical retropubic prostatectomy with lymphadenectomy had been performed in 2008 [pT3a, N0 (0/4), M0, R0, GS 5+4=9, iPSA 26.67 ng/mL], and followed by radiotherapy as of September 2009. The extended salvage lymphadenectomy was performed in April 2012 due to a PSA-level rise up to 24 ng/mL and the aforementioned PET-CT findings. A total of 22 lymph nodes were removed, among them 3 lymph nodes with metastases. In the fossa obturatoria on the right we identified a walnut-size lymph node relapse with tumour necrosis, which fully corresponded to the PET-CT scan. The PSA level subsequently dropped to 0.4 ng/mL postoperatively, and further to the current value of 0.02 ng/mL (August 2012).
