Diagnosis of prostate cancer (PCa) and adequate staging play a fundamental role for clinical and patient care. Despite major advances in biology and imaging, rectal examination and prostate-specific antigen (PSA) blood test remain the cornerstone for screening, and multiparametricmagnetic resonance imaging (mpMRI) for local staging. Recent advances in mpMRI lead to standardised interpretation and increased prescription by clinicians in order to improve detection of clinically significant PCa and select patients requiring targeted biopsies. However its indication remains controversial in biopsy-na?ve patients. Nuclear medicine is also in a continuous evolution and utilisation of new radiopharmaceutical agent like choline or ⁶⁸gallium with computed tomography or magnetic resonance imaging has led to the improvement in the detection of lymph nodes, distant metastases and prostate recurrence. Considering this very heterogneneous disease, combined utilisation of these tools will help clinicians and patients in choosing the most appropriate and personalised treatment.

Objective: Conventional treatments for benign prostatic hyperplasia (BPH) like 5alpha-reductase inhibitors and invasive surgery are associated with some obvious side effects. Conversely, evidence, though limited, has shown that alternative medicines are safer and have potential to improve the lower urinary tract symptoms (LUTS) and quality of life in addition to improving sexual dysfunction in patients with BPH. The current article aimed to include an overview of BPH, different ways of its management, and particularly its appreciation in Greco-Arab (Unani) system of medicine, one of the alternative medicinal systems.

Methods: PubMed, Scopus, ScienceDirect, Web of Sciences, Google Scholar databases and classical texts of Greco-Arab medicine were searched for data collection.

Results: In Unani system of medicine, BPH, traced under the headings of Waram unuq al-mathana (bladder neck swelling) and Insidad majra-i-mathana (bladder outlet obstruction), has been managed for centuries with herbal medicines yet demanding a comprehensive scientific validation. Among the herbs, Cucurbita pepo, Tribulus terrestris, Urtica dioica, and Linum usitatissimum are worth mentioning.

Conclusion: For achieving the goal of LUTS-free ageing men, and safer and cost-effective future management of BPH, Unani herbal medicine could hopefully prove beneficial.

Persistent hematuria could trigger urinary retention, leading the patient to the emergency department for abdominal pain, decreased urinary output, anemia, and azotemia [1,2]. Conventional bladder clot evacuation requires a three-way catheter with continuous irrigation and aspiration with a syringe or Ellik evacuator [3]. Sometimes a large and well-organized hematoma requires an open cystostomy [1,4]. We want to introduce a combined method using hydrogen peroxide as well as suction technique with an endotracheal catheter to evacuate intravesical clots.

Objective: Penile reconstruction or phalloplasty following penectomy can be offered where the functional penile length is inadequate for a man to void while standing or to have sexual intercourse. Phalloplasty is usually staged due to the complex surgical techniques required. This narrative review describes the technical concepts and summarises the contemporary outcomes following phalloplasty in this challenging cohort.

Methods: A retrospective review of the English literature was performed between January 1946 till November 2021. The data were synthesised and complemented by the expert opinion of the authors with 20 years of experience in this field. The flaps are ideally designed with an integrated urethra or alternatively, a further free flap urethroplasty can be offered. Phalloplasty is further complicated following penectomy by scarring from the previous surgery and the potential loss of structures that would normally be present at the recipient site.

Results: There are limited published data with a total of 19 men recorded in the literature. Only the radial artery forearm free flap and anterolateral thigh flap have been described in this cohort of patients. Functional outcomes including standing micturition, sensation in the neophallus, and the ability to orgasm are good. Overall quality of life and satisfaction was also good despite the high risk for long-term complications of the neophallus and donor site.

Conclusion: Phalloplasty following penectomy requires microsurgical transfer of a free flap or a pedicled flap to reconstruct a neophallus. An erectile device is inserted at a later stage to facilitate sexual intercourse, if desired. Surgical scarring from penectomy and the potential loss of vasculature that would normally be present at the recipient site may further complicate reconstruction. Surgical and functional outcomes are acceptable based on the limited published experience to date.

In Asia, about 1%-19.1% of the population suffer from urolithiasis. However, due to variations in socio-economic status and geographic locations, the prevalence and incidence have changed in different countries or regions over the years. The research for risk factors of urinary tract stones is of predominant importance. In this review, we find the prevalence of urolithiasis is 5%-19.1% in West Asia, Southeast Asia, South Asia, as well as some developed countries (South Korea and Japan), whereas, it is only 1%-8% in most part of East Asia and North Asia. The recurrence rate ranges from 21% to 53% after 3-5 years. Calcium oxalate (75%-90%) is the most frequent component of calculi, followed by uric acid (5%-20%), calcium phosphate (6%-13%), struvite (2%-15%), apatite (1%) and cystine (0.5%-1%). The incidence of urolithiasis reaches its peak in population aged over 30 years. Males are more likely to suffer from urinary calculi. Because of different dietary habits or genetic background, differences of prevalence among races or nationalities also exist. Genetic mutation of specific locus may contribute to the formation of different kinds of calculi. Dietary habits (westernized dietary habits and less fluid intake), as well as climatic factors (hot temperature and many hours of exposure to sunshine) play a crucial role in the development of stones. Other diseases, especially metabolic syndrome, may also contribute to urinary tract stones.

Objective: To determine the incidence of culture-positive urinary tract infection (UTI) after micturating cystourethrogram (MCUG). We further wanted to identify risk factors for developing a culture-positive UTI following MCUG.
Methods: A retrospective review of the available medical records of 500 paediatric patients who underwent MCUG in Perth, Western Australia was performed.
Results: Seven (1.4%) patients comprised of four females and three males developed a febrile, culture-positive UTI within 14 days following MCUG. Significant association was found for female patients, patients with neurogenic bladder, and patients with previous culture-positive UTI as developing a culture-positive UTI following MCUG. Multivariate logistic regression determined that patients were more likely to develop culture-positive UTI within 14 days following MCUG if they had a known history of UTI (odds ratio: 5.0, 95% confidence interval: 1.5-17.3, p=0.010) or had a neurogenic bladder (odds ratio: 4.2, 95% confidence interval: 1.0-17.9, p=0.049).
Conclusion: The incidence of patients who developed a febrile, culture-positive UTI following MCUG was low at 1.4%. Statistically significant and independent associations for the development of culture positive UTI were found in patients with neurogenic bladder and patients with previous culture-positive UTI. Further prospective studies are necessary to determine necessity of prophylactic antibiotics for high-risk patients, e.g., patients with neurogenic bladder or previous culture-positive UTI.

Objective: There are many models to predict extracapsular extension (ECE) in patients with prostate cancer. We aimed to externally validate several models in a Japanese cohort.

Methods: We included patients treated with robotic-assisted radical prostatectomy for prostate cancer. The risk of ECE was calculated for each patient in several models (prostate side-specific and non-side-specific). Model performance was assessed by calculating the receiver operating curve and the area under the curve (AUC), calibration plots, and decision curve analyses.

Results: We identified ECE in 117 (32.9%) of the 356 prostate lobes included. Patients with ECE had a statistically significant higher prostate-specific antigen level, percentage of positive digital rectal examination, percentage of hypoechoic nodes, percentage of magnetic resonance imaging nodes or ECE suggestion, percentage of biopsy positive cores, International Society of Urological Pathology grade group, and percentage of core involvement. Among the side-specific models, the Soeterik, Patel, Sayyid, Martini, and Steuber models presented AUC of 0.81, 0.78, 0.77, 0.75, and 0.73, respectively. Among the non-side-specific models, the memorial Sloan Kettering Cancer Center web calculator, the Roach formula, the Partin tables of 2016, 2013, and 2007 presented AUC of 0.74, 0.72, 0.64, 0.61, and 0.60, respectively. However, the 95% confidence interval for most of these models overlapped. The side-specific models presented adequate calibration. In the decision curve analyses, most models showed net benefit, but it overlapped among them.

Conclusion: Models predicting ECE were externally validated in Japanese men. The side-specific models predicted better than the non-side-specific models. The Soeterik and Patel models were the most accurate performing models.

Objective: To summarize the recent literature discussing focal therapy for localized prostate cancer.
Methods: A thorough literature review was performed using PubMed to identify recent studies involving focal therapy for the treatment of localized prostate cancer.
Results: In an effort to decrease the morbidity associated with prostate cancer treatment, many urologists are turning to focal therapy as an alternative treatment option. With this approach, the cancer bearing portion of the prostate is targeted while leaving the benign tissue untouched. Multiparametric magnetic resonance imaging remains the gold standard for visualization during focal therapy, but new imaging modalities such as prostate specific membrane antigen/positron emission tomography and contrast enhanced ultrasound are being investigated. Furthermore, several biomarkers, such as prostate cancer antigen 3 and prostate health index, are used in conjunction with imaging to improve risk stratification prior to focal therapy. Lastly, there are several novel technologies such as nanoparticles and transurethral devices that are under investigation for use in focal therapy.
Conclusion: Focal therapy is proving to be a promising option for the treatment of localized prostate cancer. However, further study is needed to determine the true efficacy of these exciting new technologies.

Objective: Our objective was to characterize the safety and efficacy of the 180 W XPS-GreenLight laser in men with lower urinary tract symptoms secondary to a small volume benign prostatic hyperplasia (BPH). Methods: A retrospective analysis was performed for all patients who underwent 180 W XPS-laser photoselective vaporization of the prostate (PVP) vaporization of the prostate between 2012 and 2016 at two-tertiary medical centers. Data collection included baseline comorbidities, disease-specific quality of life scores, maximum urinary flow rate (Q_max), postvoid residual (PVR), complications, prostate volume and prostate-specific antigen (PSA). The secondary endpoints were the incidence of intraoperative and postoperative adverse events. Complications were stratified using the Clavien-Dindo grading system up to 90 days after surgery. Results: Mean age of men was 67.8 years old, with a mean body mass index of 29.7 kg/m ². Mean prostate volume as measured by transrectal ultrasound was 29 mL. Anticoagulation use was 47% and urinary retention with catheter at time of surgery was 17%. Mean hospital stay and catheter time were 0.5 days. Median follow-up time was 6 months with the longest duration of follow-up being 22.5 months (interquartile range, 3-22.5 months). The International Prostate Symptom Score improved from 22.8 ± 7.0 at baseline to 10.7 ± 7.4 (p < 0.01) and 6.3 ± 4.4 (p < 0.01) at 1 and 6 months, respectively. The Q_max improved from 7.70 ± 4.46 mL/s at baseline to 17.25 ± 9.30 mL/s (p < 0.01) and 19.14 ± 7.19 mL/s (p < 0.001) at 1 and 6 months, respectively, while the PVR improved from 216.0 ± 271.0 mL preoperatively to 32.8 ± 45.3 mL (p < 0.01) and 26.2 ± 46.0 mL (p < 0.01) at 1 and 6 months, respectively. The PSA dropped from 1.97 ± 1.76 ng/mL preoperatively to 0.71 ± 0.61 ng/mL (p < 0.01) and 0.74 ± 0.63 ng/mL at 1 and 6 months, respectively. No patient had a bladder neck contracture postoperatively and no capsular perforations were noted intraoperatively. Conclusion: The 180 W GreenLight XPS system is safe and effective for men with small volume BPH. PVP produced improvements in symptomatic and clinical parameters without any safety concern. It represents a safe surgical option in this under studied population.

Objectives: To compare the depth of thermal necrosis after use of bipolar resection and vaporization technique comparing intra-individually bipolar loop and bipolar button electrodes.
Methods: Transurethral resection and vaporization of the prostate was performed in 55 male patients (260 specimens in total). In a standardized procedure, a bipolar resection loop was used for resection, and a bipolar button electrode was used for vaporization. Both electrodes were applied in each patient, either in the left or in the right lateral lobe. The depth of necrotic zones in the resected or vaporized tissue of each patient was measured in a standardized way by light microscopy.
Results: The mean depth with standard deviation of thermal injury caused by the loop electrode was 0.0495±0.0274 mm. The vaporization electrode caused a mean thermal depth with standard deviation of 0.0477±0.0276 mm. The mean difference of necrosis zone depths between the two types of electrodes (PlasmaButton-resection loop) was −0.0018 mm (p=0.691).
Conclusion: For the first time, we present directly measured values of the absolute necrosis zone depth after application of plasma in the transurethral treatment of benign prostatic hyperplasia. The measured values were lower than in all other transurethral procedures. Standardized procedures of measurement and evaluation allow a statistically significant statement that the low necrosis depth in bipolar procedures is independent of the applied electrodes.
