Summary

In the past two decades, the demographic crisis in Bulgaria has been widely debated. According to the National Statistical Institute (NSI), the proportion of people aged 65 and over is increasing, despite the general population decline in the country. To investigate whether the age structure of patients operated on has changed during the past 10 years and assess the need to reorganize the training of anesthetists,aretrospective study in the anesthesia electronic database of the University Hospital in Rouse was carried out. The data of anesthesia performed by anesthesiologists in 2005, 2010 and 2015 in patients aged 65 and over were summarized. The distribution of these patients by ASA Physical Classification System and frequency of complications during anesthesia were analyzed. The average annual number of anaesthesias for the three years was almost unchanged and amounted to about 5500. The proportion of patients aged 65 and over increased from 30.54%in 2005 to 35.72%in 2010, and 37.81%in 2015. The distribution of patients in according to the ASA Classification changed significantly: the percentage of patients ASAI-IIdropped from 36.19%in 2005 to 11.85%in 2015. The patients in the ASA III-IVgroups for the three analyzed years was 41.86%, 58.66%and 65.30%, respectively, and this was mainly due to the increase in the ASAIVpatients. It is necessary to build multidisciplinary teams and prepare specialized protocols for behavior in geriatric patients. It is imperative that anesthesiologists possess specialized knowledge about age-related organ changes and their effects on anesthesia.

Summary

Premature ejaculation (PE) is the most common sexual dysfunction in men, yet it is not well studied. Its frequency reaches 30% for men from 18 to 59 years of age in different countries. The aim of this article was to investigate the quality of sexual life in men with primary PE operated on with microsurgical penile denervation, using the Brief Male Sexual Functional Inventory (BMSFI). From September 2011 to March 2014, 22 patients were operated on with microsurgical penile denervation in the urology clinic of the University Hospital - Pleven and the Department of Urology at UMHAT Ruse AD. The mean result from the BMSFI in patients was 22 points preoperatively, indicating significant worsening of sexual function and quality of life in all five questionnaire domains. After surgery, the results increased to 28, 33 and 39 respectively, at 3, 6 and 12 months, respectively. Premature ejaculation not only leads to problems in controlling ejaculation but also worsens the overall sexual function and quality of life of patients.

Summary

During the last few years, prostate cancer is more frequently diagnosed in young patients. This lays emphasis on the necessity to preoperatively evaluate the sexual function in patients undergoing bilateral nerve sparing radical retropubic prostatectomy (BNSRRP). The aim of our study was to make an objective evaluation of the basic sexual function in patients with clinically localized prostate cancer and candidates for BNSRRP, using internationally validated questionnaires. We also tried to find a correlation between these questionnaires and the individual assessment of candidates, on one hand, and between comorbidities of the patients and degree of erectile dysfunction (ED), on the other hand. From January 2014 to March 2017, at the urology clinic of University Hospital – Pleven, 64 patients opted BNSRRP and reported to have preserved erectile function (EF), wishing to maintain this function after surgery. The patients’ histories and comorbidities were recorded on the day of hospitalization. The subjective assessment of the patients’ potency was compared with International Index of Erectile Function (IIEF). According to the EF domain of the IIEF, baseline EF was assessed in 28 patients. Twelve patients had mild ED, 9 patients had mild to moderate ED, seven patients had moderate, and eight had severe ED. The results showed that a significant number of patients with clinically localized prostate cancer who were candidates for BNSRRP reported to be fully potent but actually had impaired EF preoperatively. There was also a pronounced correlation between concomitant diseases and EF.

Summary

Cancer of the cervix causes internal, external compression or both of the upper urinary tract in 50-60%of patients in advanced stages. Retrograde stenting is the most widely used technique for desobstruction of the upper urinary tract in urology practice. Diversion of urine flow is an alternative, achieved by nephrostomy of one or both kidneys.We studied retrospectively 33 women with upper urinary tract obstruction caused by carcinoma of the uterine cervix operated on between March 2014 and March 2015 in the urology clinic at the University Hospital in Pleven, Bulgaria. Apercutaneous nephrostomy (PNS) was placed in 17 patients, and 11 patients hadaretrograde catheterization with ureteral stent type JJ. Five patients were treated with both methods. Placement ofa JJstent was the first choice procedure for all patients since it providesabetter quality of life. PNSimproves renal function faster than retrograde JJstenting. Therefore, the first method of choice for patients with an untreated primary cervical, uterine cancer is the placement of PNS. Retrograde JJstenting is the method of choice in patients who undergo surgery and radiation therapy withoutarelapse of the disease.

Summary

Acute appendicitis due to Enterobius vermicularis, usually known as pinworm, is very rare and affects mostly children.According to different authors, it is controversial whether pinworms cause inflammation of the appendix or appendiceal colic only.We presentacase ofa14-year-old female with three subsequent hospitalizations in 1 month due to abdominal pain in the right lower abdomen, with rebound tenderness, normal CTscan and laboratory findings. During the last hospitalization, laparoscopic appendectomy was performed. Intraoperatively multiple pinworms were found in the appendix. These were trapped byastercolith in the appendicular base inanoninflamed and histologically normal appendix. Two oral doses of mebendazole were administered postoperatively. Uneventful postoperative period and postoperative follow-up showed lack of symptoms six months after the operation. Despite the widespread idea that acute appendicitis due to Enterobius vermicularis is very rare, it should always be considered in young female patients with repeated abdominal pain in the right lower abdomen with normal laboratory and radiologic findings.

Summary

The experience accumulated with low-intensity extracorporeal shock wave therapy (LI-ESWT) from international clinical trials has demonstrated its safety, efficacy and good tolerance in treatment of erectile dysfunction (ED). The aim of this retrospective study was to investigate the effect of LI-ESWT in patients with ED after bilateral nerve sparing radical surgery for prostate cancer. Twenty-seven patients underwent bilateral nerve sparing radical retropubic prostatectomy (BNSRRP) at the clinic of urology of the university hospital in Pleven between January 2016 and December 2016. Twenty-one of these patients had pre-operative preserved erectile function (EF), as reported according to the International Index of Erectile Function (IIEF-5). Postoperatively, these 21 patients experienced a mild (18-21 points) impairment of EF. In 10 patients (group 1), LI-ESWT was performed. The procedure was performed once a week for 6 weeks with a LI-ESWT (BTL 6000 SWT Topline) instrument. The reading was obtained with IIEF-5 on the third and sixth month after the end of therapy. The other 11 patients (group 2) were used as a control group and did not receive treatment. In 5 patients in group 1, a recovery of EF (> 21 points) as per IIEF-5 was recorded at the third month after treatment. In two patients, the same score was recorded at the sixth month. No improvement was seen in three men in group 1. In the controls (group 2), a spontaneous EF improvement in four patients at sixth month was registered. Despite the small number of patients and their short-term follow-up, our initial results indicate that LI-ESWT is effective, safe and well-tolerated. It could be an alternative for early penis rehabilitation in patients who have undergone BNSRRP.

Summary

Prostate cancer (PC) is the most common type of cancer in men inanumber of countries. The choice of surgical technique for radical prostatectomy (RP) concerns both patients and urologists. The choice is not easy to make, since data is still limited due to the lack of large multicentric randomized research trials. For three years (2011-2014), 244 patients with limited prostate cancer were operated in the Urology Clinic of the University Hospital in Pleven. Robot-assisted radical prostatectomy (RARP) was performed on 35 patients (14%), open retropubic radical prostatectomy (ORP) - on 199 patients (81%), and laparoscopic RP - on 12 patients (5%). The preoperative and post-op results from the first two groups were compared. For the follow-up period of 12 months, functional results in 82 patients of the ORPgroup were compared to the results in the 35 patients of the RARPgroup. The operative time was significantly longer in the RARPgroup, and blood loss was lower. The catheter stay was shorter in patients with RARP. The percentage of significant postoperative complications was 0%in the patients with RARPand 3%in the patients with an ORP. RARPpatients demonstrated better continence: 91%vs. 87%and erectile function46%vs.40%at 12 months.
