Resultados perioperatorios y oncológicos a largo plazo de los pacientes con variantes histológicas de cáncer vesical sometidos a cistectomía radical: un análisis de emparejamiento por índices de propensión con carcinoma urotelial puro / The perioperative and long-term outcomes of patients with variant histology bladder cancer undergoing radical cystectomy: A propensity score-matched analysis with pure urothelial carcinoma

Objetivos Evaluar los resultados perioperatorios y a largo plazo de la cistectomía radical en los pacientes con variantes histológicas frente a los pacientes con patrón histológico de carcinoma urotelial puro. Métodos Los pacientes diagnosticados de carcinoma vesical con variantes histológicas fueron emparejados con aquellos diagnosticados de carcinoma urotelial puro en una proporción de 1:3 mediante un análisis de puntuación de propensión. Los 2 grupos se compararon en términos de resultados perioperatorios y morbimortalidad a largo plazo. Resultados En el presente estudio retrospectivo se incluyeron 148 individuos (37 con variantes histológicas de CU y 111 con carcinoma urotelial puro). Un total de 107 (72,3%) individuos presentaron al menos una complicación perioperatoria según la clasificación de Clavien-Dindo. Esta proporción fue similar entre los pacientes con carcinoma urotelial frente a aquellos con variante histológica (p=0,22). En cuanto a las complicaciones a largo plazo, el número de pacientes con hernia incisional clínicamente significativa que requirió cirugía (14 [12,7%] frente a 3 [8,3%]; p=0,68], estenosis uretero-intestinal/uretero-cutánea o cualquier otra complicación relacionada con la derivación urinaria aplicada (15 [13,6%] frente a 7 [19,4%]; p=0,56], o el número de pacientes que presentaron septicemia (17 [15,5%] frente a 10 [27,8%]; p=0,16] u obstrucción del tracto urinario (12 [10,9%] frente a 4 [11,1%]; p>0,99] durante el seguimiento fue similar para el grupo carcinoma urotelial y el de variante histológica. Según el análisis de supervivencia con curvas de Kaplan-Meier y el modelo de regresión de Cox univariante, el riesgo de muerte por cualquier causa era mayor en los pacientes con variante histológica que en los de patrón histológico puro (log-rank test=0,045; hazard ratio: 1,7; intervalo de confianza del 95%: 1,01-2,87; p=0,047). Conclusiones La morbimortalidad perioperatorias son comparables . (AU)

Objectives To assess the perioperative and long-term outcomes after open radical cystectomy in patients with histological variants versus pure urothelial carcinoma. Methods Patients with a variant histology carcinoma of the urinary bladder were matched through a propensity score analysis with those with pure urothelial carcinoma on a 1:3 ratio. The two groups were compared in terms of perioperative and long-term morbidity and mortality. Results Overall, 148 individuals were included in the present retrospective study (37 with variant histology and 111 with pure urothelial carcinoma). A total of 107 (72.3%) individuals presented at least one perioperative complication based on the Clavien-Dindo classification. This proportion was similar between patients with urothelial versus variant histology carcinoma (P=.22). In the long term, the number of patients with clinically significant incisional hernia requiring surgery [14 (12.7%) vs 3 (8.3%), P=.68], uretero-intestinal/uretero-cutaneous strictures or any other complication related to the applied urinary diversion [15 (13.6%) vs 7 (19.4%), P=.56], as well as the number of patients presenting with septicemia [17 (15.5%) vs 10 (27.8%), P=.16] or with urinary tract obstruction [12 (10.9%) vs 4 (11.1%), P>.99] at follow-up did not differ between urothelial versus variant histology carcinoma. The survival analysis with Kaplan-Meier curves and the univariate Cox regression model suggested that the risk of death from any cause was increased in patients with variant compared to pure urothelial histology (log-rank test=.045, hazard ratio: 1.7, 95% confidence interval: 1.01-2.87, P=.047). Conclusions Perioperative morbidity and mortality are comparable in patients with variant histology versus pure urothelial carcinoma. (AU)

Anatomic considerations of inflatable penile prosthetics: lessons gleaned from surgical body donor workshops.

Surgical implantation of an inflatable penile prosthesis (IPP) remains the gold-standard treatment for severe erectile dysfunction. The ideal surgical technique requires a thorough understanding of the relevant anatomy. This includes anatomic considerations related to, but not limited to, dissection and exposure of penoscrotal fasciae and tissues, corporal configuration, and abdominal structures. Insights obtained from pre-dissected anatomic specimens can obviate urethral injury, nerve damage, corporal perforation, inappropriate sizing, crossover, or implant malposition. We present penile implant-specific anatomic dissections and topographic landmarks identified over the last decade in the course of surgical training programs provided for IPP implantation.

Surgical and minimally invasive treatment of ischaemic and non-ischaemic priapism: a systematic review by the EAU Sexual and Reproductive Health Guidelines panel.

Surgical treatments for ischemic priapism (IP) include shunts or penile implants. Non-ischemic priapism (NIP) is usually the result of penile/perineal trauma causing an arterial fistula and embolisation may be required. We conducted a systematic review on behalf of the EAU Sexual and Reproductive health Guidelines panel to analyse the available evidence on efficacy and safety of surgical modalities for IP and NIP. Outcomes were priapism resolution, sexual function and adverse events following surgery. Overall, 63 studies (n = 923) met inclusion criteria up to September 2021. For IP (n = 702), surgery comprised distal (n = 274), proximal shunts (n = 209) and penile prostheses (n = 194). Resolution occurred in 18.7-100% for distal, 5.7-100% for proximal shunts and 100% for penile prostheses. Potency rate was 20-100% for distal, 11.1-77.2% for proximal shunts, and 26.3-100% for penile prostheses, respectively. Patient satisfaction was 60-100% following penile prostheses implantation. Complications were 0-42.5% for shunts and 0-13.6% for IPP. For NIP (n = 221), embolisation success was 85.7-100% and potency 80-100%. The majority of studies were retrospective cohort studies. Risk of bias was high. Overall, surgical shunts have acceptable success rates in IP. Proximal/venous shunts should be abandoned due to morbidity/ED rates. In IP > 48 h, best outcomes are seen with penile prostheses implantation. Embolisation is the mainstay technique for NIP with high resolution rates and adequate erectile function.

What is the effectiveness of surgical and non-surgical therapies in the treatment of ischemic priapism in patients with sickle cell disease? A systematic review by the EAU Sexual and Reproductive Health Guidelines Panel.

Sickle cell disease (SCD) is an inherited hemoglobin disorder characterized by the occlusion of small blood vessels by sickle-shaped red blood cells. SCD is associated with a number of complications, including ischemic priapism. While SCD accounts for at least one-third of all priapism cases, no definitive treatment strategy has been established to specifically treat patients with SC priapism. The aim of this systematic review was to assess the efficacy and safety of contemporary treatment modalities for acute and stuttering ischemic priapism associated with SCD. The primary outcome measures were defined as resolution of acute priapism (detumescence) and complete response of stuttering priapism, while the primary harm outcome was as sexual dysfunction. The protocol for the review has been registered (PROSPERO Nr: CRD42020182001), and a systematic search of Medline, Embase, and Cochrane controlled trials databases was performed. Three trials with 41 observational studies met the criteria for inclusion in this review. None of the trials assessed detumescence, as a primary outcome. All of the trials reported a complete response of stuttering priapism; however, the certainty of the evidence was low. It is clear that assessing the effectiveness of specific interventions for priapism in SCD, well-designed, adequately-powered, multicenter trials are strongly required.

[Bilateral intrauterine testicular torsion in a mature newborn]. / Bilaterale intrauterine Hodentorsion bei einem reifen Neugeborenen.

Bilateral intrauterine testicular torsion is an extremely rare emergency and can be difficult to diagnose due to its diverse manifestation and potential differential diagnoses. In time surgical intervention is crucial for the retention of testicular function. We present a newborn with a bilateral testicular torsion, in which one testicle could be saved after detorsion. The contralateral side showed hemorrhagic infarction and was removed. Since organ preservation is rarely successful, the surgical therapy is discussed controversially.

Long-term outcome after grafting with small intestinal submucosa and collagen fleece in patients with Peyronie's disease: a matched pair analysis.

Advanced Peyronie's disease (PD) with severe penile curvature requires grafting following plaque incision or partial plaque excision. So far, the ideal graft material has not been identified although various grafts have been studied. In this first matched pair analysis we compared the outcome after grafting with small intestinal submucosa (SIS) and self-adhesive collagen fleece (CF). We retrospectively identified 43 patients after SIS grafting with complete follow-up data sets to be eligible for the present study. A total of 43 patients after CF grafting were matched case by case to the SIS group using the degree of preoperative penile curvature as the primary matching factor. Postoperative outcome was compared with the focus on penile straightening, penile length, potency, relapse rates and long-term complications. Median degree of curvature was 80° in each group. Mean follow-up periods were 31 months after SIS and 39 months after CF grafting. The CF grafting procedure was significantly faster than SIS grafting (80 vs. 104 min, p < 0.001). No major short-term complications were observed. Both techniques gained good long-term penile straightening rates. Relapse of penile curvature was observed after SIS grafting only. Postoperative penile shortening occurred more often after SIS grafting (28% vs. 5%, p = 0.007). With a mean preoperative IIEF-5 score of 16, the SIS cohort significantly differed from the CF cohort with a mean IIEF-5 score of 19 (p = 0.016). The median IIEF-5 score improvement was higher after SIS grafting (+4.5 vs. +1, p = 0.002). Diminished penile sensation was the main long-term side effect with low rates after both procedures (9% and 7% in the SIS and CF group respectively, p = 0.100). In this first matched pair analysis both techniques showed promising long-term results. CF seems to have advantages regarding duration of surgery and preserving penile length. More comparative studies with larger collectives are desirable.

The Role of PD-L1 Expression and Intratumoral Lymphocytes in Response to Perioperative Chemotherapy for Urothelial Carcinoma.

Introduction: Immunological pathways are relevant for the effectiveness of conventional cytotoxic chemotherapy. Recently, checkpoint inhibition of the PD-1/PD-L1 axis has been shown to be therapeutically relevant in urothelial carcinoma. Objective: To monitor PD-L1 expression on tumor cells and intratumoral infiltration with CD8 positive lymphocytes during perioperative chemotherapy for urothelial cancer and to evaluate their use as potential predictive markers for chemotherapy. Patients and Methods: Sixty-four patients with muscle-invasive urothelial cancer were included in the analysis. Twenty-two patients received preoperative chemotherapy and 42 were treated in an adjuvant setting for locally advanced disease or lymph node metastases. PD-L1 status and the density of infiltration with CD8-positive cells were assessed by immunohistochemistry and analysed for their association with survival (adjuvant group) and response to chemotherapy (preoperative group). For PD-L1 positivity we used a cutoff of 10% positive tumor cells. Results: In the adjuvant group, 11 of 42 patients (26.2%) had PD-L1 positive tumor cells. Twenty-six of 42 (61.9%) patients were highly infiltrated with CD8 + lymphocytes. There was no significant evidence of an association with overall survival for PD-L1 status nor for CD8 infiltration density (p = 0.63 and 0.71). In the preoperative group, eight of the 22 (36.4%) patients were PD-L1 positive and 13 (59%) were highly infiltrated with CD8 + lymphocytes before chemotherapy. There was no evidence of associations with response or survival. Eight patients showed a pathological response to preoperative treatment. These had a significantly longer overall survival than non-responders (p = 0.01). In the preoperative group the pre-treatment expression of the immunologic markers could be compared to the post-treatment status. Only one patient showed a changed PD-L1 status and three patients a changed CD8 status. Conclusions: The tumoral expression of PD-L1 in urothelial carcinoma does not seem to be largely influenced by chemotherapy. Our data do not provide evidence that tumoral expression of PD-L1 and CD8 are useful as prognostic or predictive markers. Small sample size is the major limitation of our study.

[Conservative therapy of Peyronie's disease - update 2015]. / Konservative Therapie der Induratio penis plastica - Update 2015.

Peyronie's disease (PD) is a benign disease of the penis leading to development of fibrous plaques at the penile tunica albuginea. PD is a heterogeneous disease with variable constellation of symptoms (penile deviation, pain, penile shortening, erectile dysfunction). Due to lack of pathophysiological knowledge there is no causal therapy of PD. Surgical therapy still represents the gold standard for correction of penile deviation. Available conservative treatment options vary from oral medical therapy to minimally invasive treatments (e.g. iontophoresis) and invasive treatment modalities (e.g. intralesional therapy). A gold standard for the conservative therapy of PD does not exist due to the nonhomogeneous disease and the variable constellation of symptoms. New conservative treatment options like penile traction and also promising treatments like intralesional injection therapy with collagenase have to be further investigated and prove their efficacy in the long-term. Moreover, well-structured, standardized, randomized placebo-controlled studies have to be done for each of the treatment modalities, so that patients can be offered successful and evidence-based conservative therapies in the future.

Circulating tumor cells versus objective response assessment predicting survival in metastatic castration-resistant prostate cancer patients treated with docetaxel chemotherapy.

PURPOSE: Circulating tumor cell (CTC) counts might display a superior prognostic value for overall survival (OS) compared to objective response criteria (OR) in metastatic castration-resistant prostate cancer (mCRPC) patients. METHODS: CTCs were detected using the CellSearch™ System out of 122 samples during docetaxel chemotherapy (75 mg/m(2)) at baseline (q0) and after 1 (q1), 4 (q4) and 10 (q10) cycles, in mCRPC patients (n = 33). OR was evaluated by morphologic RECIST and clinical criteria after 4 (q4) and 10 (q10) cycles. RESULTS: For OS, analyses revealed a significant prognostic value for categorical (<5 vs. ≥5) CTC counts (q0, p = 0.005; q1, p = 0.001; q4, p < 0.001; q10, p = 0.002), RECIST (q4, p < 0.001; q10, p = 0.02) and clinical criteria (q4, p < 0.001; q10, p = 0.02). Concordance of CTC counts with OR revealed a sensitivity of 83.3-87.5 % and a specificity of 68.0-76.5 % with complementary discriminatory power for OS. Comparing CTC counts with concomitant OR at q4 in multivariate analyses, an independent prognostic value for OS was found for CTC counts (HR 3.3; p = 0.02) similar to clinical (HR 4.9; p = 0.02) and radiologic response (HR 3.4; p = 0.051). Comparing the predictive value for death, early post-treatment CTC counts at q1 demonstrated significant accuracy with an area under the curve of 79.5 % (p = 0.004) similar to CTC counts at q4 (76.7 %; p = 0.009). Radiologic and clinical response at q4 displayed accuracy similar to early CTC counts at q1 (72.2 %; p = 0.03 and 75.0 %; p = 0.02) despite low sensitivities. CONCLUSIONS: CTC counts appear to be an earlier and more sensitive predictor for survival and treatment response than current OR approaches and may provide complementary information toward individualized treatment strategies.

[Sexuality of couples 5 years after radical prostatectomy. Sexuality of patients and their partners 1 year postoperatively in sexually active couples]. / Paarsexualität 5 Jahre nach radikaler Prostatektomie. Sexualität von Patient und Partnerin bei 1 Jahr postoperativ sexuell aktiven Paaren.

BACKGROUND: Erectile dysfunction after radical prostatectomy (RPx) does affect the sexual life of patients and their partners. In our study, we evaluated sexual life over the long-term of 60 months following nerve-sparing (ns) RPx in couples who successfully performed sexual intercourse (SI) 12 months after surgery. PATIENTS AND METHOD: A total of 36 patients and their female partners who had SI prior to and 12 months after nsRPx were included in this study. Sixty months following nsRPx, couples were asked about frequency of SI, satisfaction of sexual life, usage of medical aid for erections, and sexual function [patients: IIEF-5 (International Index of Erectile Function), partners: FSFI (Female Sexual Function Index)]. RESULTS: Thirty couples (83.3%) were available for follow-up. A total of 70% of couples performed SI 60 months after nsRPx. In contrast to couples who did not have SI 60 months after nsRPx, couples who successfully had SI were more satisfied, had SI more often, had higher IIEF-5 scores, and higher frequency of bilateral ns surgery. In 80% of those patients, no medical aid except PDE-5 inhibitors were used. The partners of those patients were more satisfied with their sexual life, compared to the patients themselves. Couples, in whom the patient had IIEF-5 scores ≥19 were more satisfied, had SI more often, and the partners had higher FSFI scores, compared to couples with patients' IIEF-5 scores <19. CONCLUSION: Couples who had successfully performed SI within 12 months following nsRPx continue to have satisfying SI in the long-term. Those couples are more satisfied with their sexual life and have SI more often prior to and 12 months after nsRPx.

Surgical therapy of Peyronie's disease by partial plaque excision and grafting with collagen fleece: feasibility study of a new technique.

Surgery is gold-standard for correction of Peyronie's curvature. Grafting is preferred in advanced deviations. We present our novel surgical technique and early results of grafting with collagen fleece. Patients with stable Peyronie's disease (PD) were included. Grafting was performed by a ready-to-use collagen fleece coated with tissue sealant (TachoSil, Nycomed, Konstanz, Germany), following partial plaque excision/incision. Results of correction were documented by artificial erection. In all, n=70 consecutive patients underwent surgery. Mean patient age was 56.4 years (range: 33-72); 88.6% of patients had dorsal deviation, 11.4% lateral or ventral deviation. Grafting after partial plaque excision was performed in 61 patients (87.1%), after plaque incision in 2 (2.9%) patients. In the former patients, mean operative time was 94.2 min (range: 65-165). Totally straightness was achieved in 83.6%. Three patients required surgical drainage because of subcutaneous haematoma formation. After mean early follow-up of 5.2 days (range: 2-15), glans sensation was normal in 56 patients (91.8%). Seven patients (10.0%) underwent Nesbit procedure alone. Grafting by collagen fleece in PD is feasible and promising. Major advantages are decreased operative times and easy application. Moreover, an additional haemostatic effect is provided. However, long-term clinical outcomes are necessary to confirm these encouraging findings.

[Lichen sclerosus in the genitourinary region]. / Lichen sclerosus im Urogenitalbereich.

Lichen sclerosus (LS) is a chronic inflammatory disorder of the skin and mucosa, presenting to genitourinary physicians, pediatricians, and dermatologists. It affects both sexes with a lower incidence in men than in women. Autoimmune factors, infections, and genetic disposition are implicated in its pathogenesis. The classic clinical picture is of atrophic white plaques in the anogenital region. Pruritus, soreness, difficulty retracting the foreskin, and obstructive urinary symptoms are frequent complaints. Early histological confirmation by biopsy is recommended. The disorder is usually highly responsive to ultrapotent topical steroids. This may help arrest or delay the progressive nature of this disorder. Surgical treatment may be needed in cases of disease progression despite medical therapy. Circumcision is a successful treatment, if LS is limited to the glans and foreskin. In cases of meatal stenosis meatoplasty and in cases of urethral involvement one- or two-stage oral graft urethroplasty is necessary.

[Sexual intercourse following radical nerve-sparing prostatectomy: discrepancies between patients and their female partners]. / Geschlechtsverkehr nach radikaler nerverhaltender Prostatektomie : Diskrepanz zwischen Patient und Partnerin.

BACKGROUND: The aim of this study was to assess the frequency of sexual intercourse (SI) in couples whose men had undergone nerve-sparing radical prostatectomy. METHOD: From February 2007 to March 2008, 25 patients and their partners were asked preoperatively and 6 and 12 months postoperatively about their real and desired frequency of SI and about their satisfaction with their sex lives. RESULTS: When questioned 6 and 12 months postoperatively, patients reported higher frequencies of sexual intercourse than their female partners did (6 months: mean 4.9 vs 4.2 and 12 months: mean 4.1 vs 3.7). At both dates the frequency of SI desired by the men was on average 7.4 vs 5.5 and 5.1 by the female partners. The women appeared to be more satisfied with their sex lives than the patients (6 months: 71 vs 56% and 12 months: 67 vs 57%). CONCLUSION: Patients and their partners differ in their appraisals of sex life and SI. Therefore it is important to consider perceptions of both partners in preoperation discussions.
