Earthquakes are unpredictable natural disasters accompanied by material damage and many victims. In the case of a person remaining trapped under the collapsed material, the development of crush syndrome can occur. Crush syndrome is the result of traumatic rhabdomyolysis and is present in 2%-15% of all injured persons in an earthquake. It is not easy to recognize, and proper treatment is challenging. Persons who have a clear crush injury and/or have been immobilized for more than four hours should be considered potential victims of crush syndrome. Therefore, knowledge about crush syndrome must be comprehensive and accessible to all parties involved. In this paper, the management of crush syndrome victims, which includes the principles of triage, and medical and logistic principles as well, is presented. Triage principles are presented at the level of triage priorities, places, and diagnoses. Medical principles, crucial for crush syndrome, are presented regarding the duration of compression and time before or after extraction of the patient. Logistic principles provide an overview of the priorities and modes of transport in relation to distance of health institutions, and the importance of management and education associated with crush syndrome. Each country with recognized disasters (natural or man-made) in which crush-related victims are expected, will benefit if the knowledge about triage, medical and logistic principles for crush syndrome is incorporated in their educational programs and regularly updated.

Benign prostatic hyperplasia is one of the most common diseases in men, with a prevalence rate of 50% in their 50s to 80% in their 80s, and is mostly treated with chronic drug therapy. The aim of this study was to analyze adverse drug reactions (ADR) to drugs used in benign prostate hyperplasia (BPH) treatment reported to HALMED from 2008 to 2021. Data on ADR reports in Croatia were obtained from the VigiFlow national database and on the use of drugs for BPH in Croatia from Drug Utilization Reports from HALMED. In the observed period, the number of reports on each BPH drug, total number of reports, seriousness of reported ADR, patient age and sex, type of reporter, and most reported ADRs were analyzed. Results showed that 438 ADR reports were received, of which 45.95% on tamsulosin as the most frequently used drug for BPH. Of all reports, 84% were non-serious, 96% were reported in men and 82% in patients older than 45 years. The most frequently reported ADRs were consistent with the known safety profile of BPH drugs. Pharmacists were the most common (47%) reporters of ADRs for BPH drugs, while 33% were reported by physicians. Analysis of the reported ADRs showed that most frequently reported ones were in line with the known safety profile of BPH drugs. However, given the prevalence of the disease and the extent of the use of BPH drugs, it could be argued that the number of reports could be higher (i.e., 34 reports/year). Reporting on ADRs is necessary to better understand the safety profile of drugs in the post-authorization period, and more information on the safe use of medicines could be collected by raising awareness of healthcare professionals.

Today, percutaneous nephrolithotomy (PCNL) is a standard procedure in the treatment of large kidney stones. Development of the procedure began in 1976 with publication of the first reports, while turning point came in 1985 when the first 250 cases were described. Subsequently, PCNL has become standard in the treatment of kidney stones instead of open surgery. Numerous modifications of the procedure have been developed with advancement of modern technology. Nevertheless, there is still the necessity for clearer understanding of differences and circumstances of choice among different techniques. There are significant differences in the instruments used for the procedure, so we distinguish standard PCNL (working channel of 24-30 Fr), mini PCNL (working channel of 11-18 Fr), ultra-mini PCNL (working channel <15 Fr), and micro PCNL (working channel <6 Fr). With the development of flexible ureteroscopy (FURS), a combined method is also being developed, i.e., Endoscopic Combined IntraRenal Surgery (ECIRS, PCNL + FURS). Furthermore, each procedure can be performed in prone or supine position. The aim of this paper is to point out the similarities and differences, the advantages and disadvantages of different techniques, with an additional aim to present our experience and current standard practice in kidney stone treatment.

New minimally invasive procedures to treat benign prostatic hyperplasia (BPH) have been developed in the last 20 years. With the introduction of laser enucleation techniques in prostate surgery, previous standard surgical procedures (open retropubic or transvesical adenectomy and transurethral resection of the prostate) have become less relevant, especially in case of very large prostates. The objective of this paper is to describe the experience and results of thulium:YAG laser application in BPH treatment in our department. In the last five years, 246 patients underwent thulium:YAG laser enucleation of the prostate (ThuLEP) due to BPH or lower urinary tract symptoms following complete urologic evaluation. The mean age of our patients was 73 (range 51-95) years and mean duration of surgery was 92 minutes. The mean weight of enucleated tissue was 73 grams. A low rate of intraoperative and early postoperative complications and short length of stay proved minimal invasiveness of this procedure, which results in significant improvements in urodynamic parameters and substantially reduces the post-void residual urine volume. The most important surgical and technical characteristics (enucleation and low-power laser application) make ThuLEP a safe and efficient surgical method not limited by the prostate volume. ThuLEP has a potential to displace the current standard surgical procedures to treat BPH.

The aim of this study was to compare the number of biopsy and surgical procedures on prostate, as well as the number of newly diagnosed, histologically confirmed cases of prostate cancer during the COVID-19 pandemic at Zagreb University Hospital Center (UHC). We retrospectively collected and processed a total of 1344 histopathologic findings of the prostate at the Zagreb UHC. Our results show that during the COVID-19 pandemic, there was a statistically significant decrease in the absolute number of biopsy and surgical procedures on prostate at Zagreb UHC, and so was the number of newly diagnosed, histologically confirmed cases of prostate cancer. During the observed time of the pandemic (March 19, 2020 to December 31, 2020), there was a 37.5% decrease in the absolute number of newly diagnosed prostate cancer cases compared to the same period of the previous year (March 19, 2019 to December 31, 2019). To our knowledge, this is the first study of this kind that is based on the number of prostate cancer diagnoses in Croatia. By observing the early period of the pandemic, our results provide important guidelines for monitoring and understanding the long-term consequences of the pandemic on the prostate cancer morbidity and mortality.

Kidney transplantation is the treatment of choice in eligible patients with end-stage kidney disease. Prostate cancer (PC) is the second most common cancer in men worldwide. The prevalence of chronic kidney disease worldwide is 13.4%. The management of localized PC in these patients is challenging due to immunosuppressive therapy and pelvic graft localization. High graft and recipient survival rates have resulted in higher numbers of these patients in our everyday practice. A retrospective analysis of male patients who had undergone kidney transplantation at our center between 2002 and 2022 and were diagnosed and treated for PC was performed. We analyzed the incidence, treatment methods, and follow-up of PC patients in this population. A total of 1079 male patients were transplanted. PC was diagnosed in 12 patients (8 after and 4 before transplantation). The incidence of PC was 1.11%. Radical prostatectomy was performed in 11 patients, and one patient was treated with radical radiotherapy. Eleven patients had stable graft function; 1 graftectomy was performed, unrelated to PC. Three patients were indicated for salvage radiotherapy, one is in process for prostate-specific membrane antigen positron emission tomography (PSMA PET CT), and 7 patients are in follow-up and without recurrence. Radical prostatectomy is a safe treatment method for localized PC in kidney transplant recipients, which does not impair graft function and survival.

Coagulation disorders in critically ill patients presenting with bleeding can be multicausal. The drugs applied can interfere and impair the coagulation cascade. Point-of-care (POC) coagulation assays may resolve difficult therapeutic situations in critical illness. We report on a 73-year-old critically ill male patient with massive hematuria after bladder lithotripsy. The patient was on low molecular weight heparin therapy due to recent pulmonary embolism. He was subjected to repeated surgical hemostasis which was ineffective despite massive transfusion protocol and normal standard coagulation profile. Additional POC coagulation assays were obtained and were indicative of platelet dysfunction. We revised his medical therapy and suspected the possible drug influence on platelet aggregation. After discontinuation of target drug, platelet aggregation increased whereas hematuria stopped. Coagulation disorders in intensive care unit patients are often multifactorial. Standard laboratory tests are unreliable in complex refractory bleeding and may result in inappropriate therapeutic decisions. Stepwise approach with assessment of clinical parameters, present therapy, and a combination of POC coagulation tests is the key to optimal therapeutic management.

According to the International Continence Society, stress (static) urinary incontinence is defined as any involuntary loss of urine on effort or physical exertion, due to which intravesical pressure overcomes urethral pressure, with no detrusor activity. Urodynamic testing accurately assesses the function of the bladder and urethra. The urodynamic assessment includes three tests: cystometry, uroflowmetry and profilometry (determination of urethral pressure profile). Prior to urodynamic assessment, it is mandatory to rule out urinary tract infection since it is an invasive test. Urethral profilometry is a technique that measures pressure in the urethra and bladder at rest, during stressful actions, and during the act of miction. Its main purpose is to evaluate the sphincter mechanism. During the examination, a special catheter is used, which is being slowly pulled out from the bladder neck throughout the urethra, with continuous recording of intraurethral pressure. In addition to measuring urethral pressures, stress urinary incontinence is also very successfully proven by the cough test and Bonney test. If, on forced cough, the urine escapes uncontrollably, and continence is restored by finger lifting the neck of the bladder, the diagnosis of static incontinence is confirmed. At our urogynecologic clinic, urodynamic examination is being routinely performed. In the present study, we included patients previously treated for urinary stress incontinence and compared their results of urodynamic assessment to the results of Bonney test. Of the 43 subjects in whom stress incontinence was proven with Bonney test, we recorded an appropriate profilometry result in 13 cases.

Chronic kidney disease (CKD) is among the most significant health problems, with the associated cardiovascular disease and bone metabolism disorders being the leading cause of morbidity and mortality in these patients. The aim of the study was to determine markers of bone turnover in patient sera (phosphates, calcium, alkaline phosphatase, parathyroid hormone and osteoprotegerin (OPG)) in all stages of kidney failure including kidney transplant recipients. We also wanted to determine whether dialysis vintage affects recovery of bone markers one year after transplantation. There were 164 study patients, whereas 30 healthy individuals served as a control group. Serum OPG progressively increased with decline of the glomerular filtration rate. The highest OPG concentration was recorded in dialysis group. We observed a statistically significant OPG increase in stage 2 CKD. In kidney transplant group, there was positive correlation between OPG and dialysis vintage. We also found that serum OPG was lower in patients treated with dialysis for less than 4 years prior to transplantation. We confirmed that CKD-mineral and bone disorder began in stage 3 CKD with parathyroid hormone and OPG elevation, and a statistically significant OPG increase in stage 2 CKD might be an early sign of CKD-mineral and bone disorder. Dialysis vintage longer than 4 years is associated with more significant disturbances in mineral and bone metabolism.

The aim of this study was to compare the number of newly diagnosed, histopathologically confirmed cases of urothelial carcinoma before and during the COVID-19 pandemic at the Zagreb University Hospital Center. We retroactively collected and analyzed 300 histopathologically confirmed urothelial carcinoma between January 1, 2019, and December 31, 2020, at the Department of Pathology and Cytology, Zagreb University Hospital Center. Our results showed that during the COVID-19 pandemic, there was a statistically significant decrease (p=0.001; χ2-test) in the number of newly diagnosed, histopathologically confirmed cases of urothelial carcinoma at the Zagreb University Hospital Center. There was a decrease in the absolute number of newly diagnosed urothelial carcinoma by 25.8% in the observed time of the pandemic (March 19, 2020 to December 31, 2020) as compared to the same period of the previous year (March 19, 2019 to December 31, 2019). Our study is the first study of this type based on the number of newly diagnosed urothelial carcinoma in Croatia. Observing the early period of the pandemic, our results provide important foundation for future monitoring and long-term consequences of the pandemic on the morbidity and mortality of urothelial carcinoma.
