ABSTRACT

There is increasing evidence that Chlamydia trachomatis (CT) infection can directly affect male fertility. However, only few have investigated the effects of CT on semen parameters, and mostly with inconclusive results. The main aims of this study were to identify CT inside spermatozoa, and the possible pre and post antibiotic treatment effects on the overall semen parameters. We developed a flow cytometric method for the detection of CT inside spermatozoa (SPI™). Briefly, sperm cells were fixed, membrane permeabilized and DNA was loosened using DNAse. Sperm cells were incubated with a primary monoclonal antibody against CT and with a secondary fluorescent antibody (vs primary), and analysed using a flow cytometer. Of 2415 infertile individuals, 48.61% were found positive for CT. 170 CT+ samples were included in the CT antibiotic treatment study. 78.82% (134/170) of the CT+ showed a significant reduction in the percentage of the iCT infected spermatozoa after the antibiotic treatment; 59.70% (80/134) decreased to non-detectable levels. Spermcount data were also recorded. Spermatozoa morphology (normal and teratozoospermia index, TZI) and motility (fast progressive and non-progressive spermatozoa) were statistically significant altered in CT+ pre-treatment vs control group. CT antibiotic treatment showed statistically significant effects on normal spermatozoa morphology, mid-piece and tail defects, and TZI. The study demonstrated that semen flow cytometric analysis of semen could be a valuable tool for faster and accurate identification of individuals with asymptomatic CT infection. It also identified a positive effect of antibiotic therapy on semen parameters, that could help males with infertility.

ABSTRACT

The fascial structure around the prostate has been a controversial issue for several decades, but its role in radical prostatectomy is crucial to achieving successful nerve-sparing surgery. One of the fasciae surrounding the prostate is Denonvilliers' fascia, forming its posterior border with the rectum and enclosing along its layers several fibers of the neurovascular bundle. This review focuses on embryological and anatomical points of Denonvilliers' fascia, aiming to provide a summary for the operating general surgeons and urologists of this area.

ABSTRACT

Erectile dysfunction (ED) is a disorder that affects the quality of life and the sexual relations of more than half of the male population aged over 40 years. The prediction regarding the incidence of ED is devastating as it is expected that this disorder will affect more than 300 million men in the next five years. Several studies have suggested the use of stem cells for the treatment of ED and showed that this type of treatment is promising in terms of damaged tissue repair as well as of clinical efficacy; however, there are several gaps in the knowledge and evidence is lacking. In order to highlight a few of them in this review, we performed a research of the literature focusing on currently available clinical studies regarding the clinical efficacy of stem cell administration for the treatment of ED. We reviewed the methods of administration, the cell types used in the performed clinical trials and the safety and efficiency of such procedures. We conclude that there are rapidly expanding and promising results from the reported clinical studies indicating that stem cells could indeed be a potential treatment for patients with ED although more studies are necessary.

ABSTRACT

Background: The current treatment of Erectile Dysfunction (ED) is mainly based on the use of drugs that provide erections shortly after use but they do not really treat the problem. Stem cell therapy is a novel treatment with regenerative properties that can possibly treat erectile dysfunction. Methods: Five patients with erectile disease were treated with Adipose-Derived Stem Cells (ADSCs) and Platelet Lysate Plasma (PLP). ADSCs were obtained through abdominal liposuction and PLP was prepared after obtaining blood samples from peripheral veins. Erectile function was evaluated with the International Index of Erectile Function questionnaire (IIEF-5) questionnaire, penile triplex at the 1st, 3rd, 6th and 12th month post-treatment. A CT scan of the head, thorax and abdomen was done before treatment and at the 12th month. Results: IIEF-5 scores were improved in all patients at the 6th month although not in the same pattern in all patients. Peak Systolic Velocity (PSV) also improved at the 6th month in all patients but also with different patterns in each patient, while End Diastolic Velocity (EDV) was more variable. Two patients decreased the treatment they used in order to obtain erection (from Intracavernosal injections (ICI) they used PDE-5Is), two had unassisted erections and one had an initial improvement which decreased at the 6th month. There were no side effects noted. Conclusions: Stem cell therapy in combination with PLP appears to show some improvement in erectile function and has minimal side effects in the short term.

ABSTRACT

Erectile dysfunction (ED) affects more than 30 million men; endothelial dysfunction plays a significant role in EDs pathogenesis. The aim of this study was to administer mesenchymal stem cells (MSC) derived from adipose tissue and platelet lysate (PL) into patients with erectile dysfunction. This pilot study enrolled eight patients with diagnosed ED. Patients enrolled were suffering from organic ED due to diabetes melitus, hypertension, hypercholesterolaemia, and Peyronie disease. The patients were distributed in 2 groups. Patients in group A received adipose derived mesenchymal stem cells (ADMSC) resuspended in PL while patients in group B received only PL. ADMSCs were isolated from patients' adipose tissue and expanded. In addition, blood sampling was obtained from the patients in order to isolate platelet lysate. After the application of the above treatments, patients were evaluated with an International Index of Erectile Function (IIEF-5) questionnaire, penile triplex, and reported morning erections. After MSCs and PL administration, patients presented improved erectile function after 1 and 3 months of follow-up. A statistically significant difference was observed in the IIEF-5 score before and after administration of both treatments after the first month (p < 0.05) and the third month (p < 0.05). No statistically significant difference was observed in the IIEF-5 score between group A and B patients. All patients were characterized by improved penile triplex and increased morning erections. No severe adverse reactions were observed in any patient except a minor pain at the site of injection, which was in the limits of tolerability. The results of this study indicated the satisfactory use of MSCs and PL in ED. MSCs in combination with PL or PL alone seems to be very promising, especially without having the negative effects of the current therapeutic treatment.

ABSTRACT

Lateral calcaneal flap is an established surgical option for coverage of lateral calcaneum and posterior heel defects. Lateral calcaneal flap vascularization and innervations are based on lateral calcaneal artery neurovascular bundle, that is, lateral calcaneal artery, small saphenous vein, and sural nerve. Anatomical research has allowed exploration of its many advantages but can also lead to its various modifications, permitting a wide variety of clinical applications. In this paper the authors report an anatomical and clinical study on lateral calcaneal artery course and lateral calcaneal flap clinical applications. Anatomic part of our study focused on lateral calcaneal artery course and optimization of surgical technique for flap harvesting. Data were used for design of lateral calcaneal flap in 5 patients. Our results were satisfactory in terms of coverage adequacy, perioperative morbidity, and functional and aesthetical outcome.

ABSTRACT

The Authors report a complete study concerning complications, the imaging and functional results, the clinical outcome and the quality of life in patients treated with VIP. 95 patients with localized bladder TCC (T2N0M0) were evaluated. Follow up points were 1st, 3rd, 6th, 12th, 18th, 24th and 36th month with clinical and ultrasound evaluation. At 6th, 12th and 36th month CT pyelography and urodynamic evaluation were performed and we used a questionnaire for subjective bladder function and the EORTC QLQ C-30 questionnaire to evaluate quality of life. Perioperative complications were ileus (2 patients; 2.1%) (Clavien Grade IIIb), one postoperative death (1.0%) (Clavien Grade V) and a resuscitated cardiac arrest (1.0%) (Clavien Grade IVa). Postoperative complications were incisional hernias (n=4 patients; 4.21%) (Clavien Grade I) and hydronephrosis in five patients (5.26%) due to ureteric/neobladder stricture (Clavien Grade IIIb). Urine retention due to neobladder neck stenosis was observed in one patient (1.0%) (Clavien Grade IIIb) and an ileo-neobladder fistula in one (1.0%) patient (Clavien Grade IIIb). During follow up there were two cancer related deaths (2.1%). According to urodynamic evaluations neobladder capacity increased, end-filling pressure and Qmax decreased while residual urine and the number of intrinsic contractions remained stable. Continence rates and quality of life were high and stable during follow up. VIP technique for bladder substitution is a relatively easy technique with low rate of complications, good functional results which respect the patient's quality of life.

ABSTRACT

Horseshoe kidney (HSK) is the most common renal fusion, which is characterized by three anatomic anomalies: ectopia, malrotation and vascular changes. Patients with HSK are prone to a variety of complications, genitourinary and non-genitourinary. In this paper, the anatomy of HSK is delineated with a great emphasis on its blood supply. After reviewing the literature, the arterial supply patterns found by each author were categorized according to the classification system proposed by Graves. The majority of HSKs were found to be supplied by renal arteries derived from the abdominal aorta below the isthmus or by vessels originating from the common iliac arteries. In addition, the abnormalities associated with HSK are highlighted and classified in anatomical variations, congenital anomalies as well as in pathologic conditions related to HSK.

ABSTRACT

OBJECTIVE: To investigate the anatomical variability of the palatine structures in Greek population. MATERIAL AND METHODS: 71 Greek adult dry human skulls were examined to detect the position of the greater palatine (GPF) and lesser palatine foramina (LPF) related to adjacent anatomical landmarks. RESULTS: The perpendicular distance of the GPF to the midline sagittal suture was 1.53 cm and 0.3 cm from the inner border of the alveolar ridge. The mean distance from the posterior palatal border was consistent 0.46 cm on the right and 0.47 cm on the left side of the skulls. In the greater majority of the skulls (76.2%), the GPF were between proximal-distal surfaces of the 3rd maxillary molar. A single LPF was observed in 53.45% of the skulls, two LPF were observed in 31% of the skulls bilaterally and five LPF were rare (2.1%). The commonest position of LPF was at the junction of the palatine bone and the inner lamella of the pterygoid plate (71.9%). CONCLUSION: Our results can help clinicians localize the palatine foramina in patients with and without maxillary molars and to predict the depth of a needle to anaesthetise the maxillary nerve with greater success when performing surgical procedures in the hard and soft palate.

ABSTRACT

The present study describes analytically a rare case in which lingual and facial arteries arise together from an external carotid artery in a common trunk. Thirty anatomic dissections were performed on 15 cadavers in the macroscopic laboratory in the Department of Anatomy of the Medical School of National and Kapodistrian University of Athens. One common trunk from which originated lingual and facial arteries was found. The frequency of this morphology is measured at 6 per cent. The length of the common trunk is measured at 7.3 mm between its origin and its diversion at the facial artery and lingual artery, its diameter at 2.8 mm, its distance from carotid bifurcation at 7.9 mm, and from the superior thyroid artery at 3.3 mm. At the left side of the neck region, facial and lingual arteries arose separately. The anatomic variations of the branching pattern of the external carotid artery and the micrometric values of the vessels are especially important as a result of the numerous operations performed in the neck region that implicate various specialties such as general surgery, head and neck surgery, plastic surgery, and maxillofacial surgery.

ABSTRACT

AIM: To present in human cadavers the anatomical basis of penis lengthening operations and reproduce this technique in a group of patients. MATERIALS OF STUDY: Penis ligaments in ten human cadavers were identified and dissected releasing the penis from its fixation to pubic arch. The same technique was applied to a group of forty patients that demanded a penis lengthening operation. RESULTS: The dissection of penis ligaments increases the distance pubic bone-tip of the penis for 3.1 +/- 0.6 cm. In patients, the increase in length 12 months post-operatively was 3.5 +/- 1.3 cm (2.3-5.1 cm) flaccid and 1.8 +/- 1.4 cm (1.4-3.2 cm) erect. There was a statistically significant difference (p < 0.005) between preoperative and postoperative status. The overall satisfaction rate was 67.5%. DISCUSSION: Cadavers study shows that this technique offers significant mobilization of the penis with a 3 cm gain, while on living tissue it has similar results. Anatomical parameters that might influence the final outcome of the operation are the length (antero-posterior dimension) of the pubic arch (corresponds to the length of the ligament), its angle with the horizontal level, the amount of the fatty tissue in the pubic area and the angle of the repositioning of the penis. CONCLUSIONS: Division of ligaments of the penis increases its apparent length. Significant anatomical parameters are the length of the pubic arch, its angle with the horizontal level, the amount of the fatty tissue in the pubic area and the angle of the repositioning of the penis.

ABSTRACT

OBJECTIVES: To assess the efficacy and the simplicity of a modified open transvesical prostatectomy for large prostates (>80 mL). METHODS: A total of 165 patients with benign prostatic hyperplasia were treated with transvesical prostatectomy through a 3-cm incision. Prostate size was 85-144 cm(3) (mean 101 cm(3)). Surgery is performed as the standard transvesical prostatectomy but skin incision is much smaller (approximately 3 cm), whereas muscle incision underneath is about 7 cm long. Prostate adenoma was removed with finger dissection without the placement of hemostatic sutures. RESULTS: Operation time was 15-36 minutes (mean 24 minutes). Catheter was removed on the third day and patients left the hospital after successful voiding. Preoperative hematocrit was 40.6-49.2 (mean 43.4), while postoperative hematocrit was 28.3-42.4 (mean 38.3). Transfusion rate was 0-3 blood units (mean 1 U). Mean preoperative flow was 11.5 cm/s and mean postoperative flow was 22.3 cm/s. Mean IPSS score improve from 28 preoperatively to 15 postoperatively. CONCLUSIONS: Open transvesical prostatectomy with a 3-cm incision is a minimally invasive technique for the treatment of large prostates (>80 mL) in which transurethral prostatectomy or laser prostatectomy may not be the first choice.

ABSTRACT

OBJECTIVES: To measure the quality-of-life (QoL) outcome and urinary and sexual function and bother after radical cystectomy and different types of urinary tract reconstruction (Bricker vs modified S-pouch neobladder), also assessing differences between them and a normal population. PATIENTS, SUBJECTS AND METHODS: Two groups of patients with bladder cancer were assessed; group 1 comprised 58 (mean age 65 years, mean follow-up 28 months) with an ileal conduit diversion, and group 2, 50 (mean age 61 years, mean follow-up 26 months) with a modified S-pouch neobladder. All were disease-free. Group 3 comprised 54 healthy subjects (a control population) of similar age, gender and comorbidities other than bladder cancer. A QoL questionnaire was used to study changes in QoL, and a specific questionnaire for urinary and sexual function and bother was also constructed. RESULTS: There were no differences in the QoL scores among the three groups; group 3 (control) tended to have a better QoL for all domains except emotional functioning. Urinary function was seriously affected in group 1, with more daytime leakage than in groups 2 and 3 (37.8% vs 10%, P = 0.005, and 9.3%, P = 0.01), night loss of urine (39.5% vs 28%, P = 0.07, and 3.7%, P = 0.002) and urine odour (58.6% vs 4%, and 5.5%, both P = 0.001). Patients in group 2 differed from healthy individuals only in night loss of urine. Consequently urinary bother was more pronounced in group 1, as fewer were satisfied (68.9% vs 86% and 83.2%, both P = 0.03). Sexual function was seriously and similarly affected in groups 1 and 2; the erection rate was 28.9% for group 1, 35.5% for group 2 (P = 0.1) and 83.3% in group 3 (P = 0.003), while firm erections were present at 17.7%, 22.2% (P = 0.2) and 83.3% (P = 0.002). Women reported equivalent dysfunction in all three groups (15.4%, 20% and 16.6%, P = 0.3). Sexual desire was also equal in all groups (48.2%, 50% and 48.1). Patients in group 1 expressed more bother, while those in group 2 seemed more satisfied by their sexual life (84.4%, 68% and 68.5%, P = 0.04). CONCLUSIONS: Radical cystectomy does not affect QoL whichever urinary reconstruction is used, and this implies a determination by the patients to live and adjust to their new conditions. On the contrary, urinary and sexual function are affected and related to the method used to reconstruct the urinary system.
