Sacral neuromodulation (SNM) is a safe, efficacious, and minimally invasive advanced therapy that involves electrical stimulation to sacral nerve root to modulate neural pathway. Indications for SNM ...include symptoms of overactive bladder (OAB), urinary incontinence, urinary retention, urgency and frequency and, regarding bowel dysfunction, fecal incontinence . In Europe and Canada, indication is also established for chronic constipation. The mechanism of action is still not fully elucidated and complete understanding is yet to be determined. It is proposed that SNM modulates neural circuits in both central and peripheral pathways, thus having an impact on the brain, as well as on the bladder-targeting neuronal activity. Another possible significant effect on irregular bladder activity is through inhibition of the bladder afferent pathways by stimulation of the pudendal nerve. Over the past two decades, with more than 300 000 treated patients, SNM has confirmed its efficacy to relieve refractory OAB symptoms, as well as urinary retention or fecal incontinence. First SNM applications in Croatia were uneventful and we are glad to offer our patients this novel therapy in the future.Sacral neuromodulation (SNM) is a safe, efficacious, and minimally invasive advanced therapy that involves electrical stimulation to sacral nerve root to modulate neural pathway.

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.Kidney transplantation is the treatment of choice in eligible patients with end-stage kidney disease.

Background: Non-obstructive azoospermia (NOA) is a form of male infertility caused by disorders of the testicular parenchyma and impaired spermatogenesis. This study aimed to investigate the nature ...of Leydig cell changes in patients with NOA, especially whether their actual proliferation occurred. Methods: 48 testicular biopsies from infertile patients with NOA and 24 testicular biopsies originating from azoospermic patients suffering from obstructive azoospermia (OA) were included in the study. Leydig cells and their possible proliferative activity were analysed by immunohistochemistry and morphometry (stereology). Results: Unlike in the OA group, Leydig cells in NOA patients were sometimes organised into larger clusters and displayed an abundant cytoplasm/hypertrophy. Moreover, significant fibrosis of the interstitial compartment was demonstrated in some NOA samples, often accompanied by inflammatory cells. Stereological analysis showed no increase/proliferation of Leydig cells; on the contrary, these cells decreased in number in the NOA group. Conclusions: The decrease in the number of Leydig cells can be explained by previous inflammatory changes within the testicular interstitium and consequent interstitial fibrosis. The interstitial fibrosis might have a deteriorating effect on Leydig cells.
The aim of the review is to establish sexual and reproductive functions in men with spinal cord lesion (SCL). Many sexual and reproductive dysfunctions may be found in these patients including ...individual's low self-esteem, delay of orgasm, erectile or ejaculatory disorder and abnormalities of semen, which are characterized by lower sperm motility or viability. Owing to improvements in physical medicine and rehabilitation, the focus has been shifted from keeping patients alive towards ensuring the quality of life and improvements of sexual dysfunctions and later reproduction. Erectile dysfunction can be treated by using phosphodiesterase-5 inhibitors, intracavernosal injections, vacuum devices and penile prostheses. Semen can be retrieved from anejaculatory patients by medically assisted methods utilizing penile vibratory stimulation, electroejaculation, prostate mas-sage, or surgically. Although there is low chance for pregnancy in natural way in most of SCL pa-tients, fatherhood is possible through the introduction of assisted medical management. By use of various medical, technical and surgical procedures for sperm retrieval combined with assisted reproductive methods, high pregnancy rates have been reported comparable to those in able-bodied subfertile patients. Nevertheless, future studies are needed to improve semen quality and methods of assisted ejaculation in patients with SCL.
Erektilna je disfunkcija (ED) nesposobnost postizanja i/ili održavanja erekcije dovoljno čvrste za zadovoljavajući spolni odnos. Posebno mjesto u dijagnostici i liječenju zauzimaju bolesnici sa ...srčanim tegobama. ED je „marker“ u otkrivanju srčanih bolesnika, a javlja se prosječno 3 – 5 godina prije prvih srčanih tegoba. Liječenje ED-a danas je uspješno te je većina bolesnika zadovoljna svojim spolnim životom. Ipak, treba biti oprezan prilikom propisivanja simptomatske terapije kod srčanih bolesnika te uvijek uključiti i kardiologa u procjeni srčane funkcije.
To analyze the differences in the population of perivascular and peritubular Leydig cells (LC) and the number of Reinke's crystals (RCs) in the testicles of infertile men with non-obstructive and ...obstructive azoospermia.
This retrospective case-control study was conducted on the testicle tissue of infertile men with obstructive (n=10) and those with non-obstructive azoospermia (n=100). Stereological analysis was performed on 7-μm paraffin sections. Measurements were carried out by using the Weibel multipurpose test system.
Patients with non-obstructive azoospermia had a higher total/absolute number of LCs in the perivascular space (P=0.034). In these patients, no significant difference was found in the total and absolute number of RCs between the peritubular and perivascular space. Patients with obstructive azoospermia had around three times higher absolute number of RCs in both the peritubular and perivascular spaces (P=0.002; P<0.001) than non-obstructive group.
Our results suggest that in patients with non-obstructive azoospermia LCs migrated or had different densities in the peritubular and perivascular space compared with patients with obstructive azoospermia. Moreover, the lower number of RCs could imply their utilization by LCs in testosterone production.
Nekada smo benignu hiperplaziju prostate smatrali glavnim uzrokom problema s mokrenjem kod muškaraca. Danas koristimo naziv simptomi donjeg urinarnog trakta jer se pokazalo kako je benigna ...hiperplazija prostate samo jedan od etioloških čimbenika. Kvalitetna dijagnostička obrada simptoma uputit će nas u pravom smjeru kako bismo mogli individualizirati terapiju. Za pacijente koji imaju indikaciju za kirurško liječenje danas postoji nekoliko operativnih tehnika. Otvorena jednostavna prostatektomija najstariji je i dokazano učinkoviti zahvat. Transuretralna resekcija prostate je zlatni standard liječenja. Laserska tehnologija danas stoji uz bok zlatnom standardu, a pojavile su se i tehnike minimalno invazivne kirurgije koje pružaju prednosti niskog morbiditeta i kratkotrajne hospitalizacije.

Kidney transplantation is the treatment of choice for patients with end-stage renal disease. However,
it took years and numerous attempts to achieve success, for the kidney to function well and for ...the patient to survive after the transplantation. Following this breakthrough made by Murray in 1954, the introduction of immunosuppressive therapy and tissue typing has significantly improved this program. Today we have new challenges in maintaining or improving a kidney transplant program, one of which is COVID-19 infection. This review presents the history and current status of kidney transplantation, emphasizing the Croatian Kidney Transplant Program.
