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.

urinary and sexual function and bother was also constructed. RESULTSThere 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). CONCLUSIONSRadical 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. KEYWORDSquality of life, bladder cancer, radical cystectomy, ileal conduit, modified S-pouch. OBJECTIVESTo 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

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.

Introduction: Impacted stones are those that remain unchanged in the same location for at least 2 months. Materials and Methods: We evaluated 42 patients with impacted ureteral stones, and followed them for two and a half years to check for long-term results. The calculi location included all three segments of the ureter (proximal, mid and distal). Patients’ age ranged from 22 to 83 years (mean 52.5 years). Primarily, patients were manipulated with extracorporeal shock wave lithotripsy (ESWL) in situ, or following stenting. If the result was not satisfactory, then we proceeded to retrograde ureteroscopy and ureterolithotripsy. Open ureterolithotomy was our final choice. Results: Thirty-six of the 42 patients (85.7%) were stone-free without the need of an open procedure. Follow-up period ranged from 10 up to 40 months, with a median period of 30 months and was achieved in 30 patients (71.4%). Stone recurrence was noted in 4 cases, while hydronephrosis without evidence of stone presence in 2. Conclusions: The initial approach for the treatment of impacted lithiasis should be attempted by ESWL. If this fails, alternative therapeutic solutions such as endoscopy can result in removal of the stone.

Objective: Stricture of the vesicourethral anastomosis remains a well-documented complication after radical retropubic prostatectomy. Materials and Methods: We performed a retrospective study of 294 patients with prostate cancer who underwent radical retropubic prostatectomy. Possible correlations between anastomotic stricture formation, tumor stage, positive surgical margins, number of anastomotic sutures, bladder neck preservation, urine leakage, previous prostate surgery and/or intraoperative blood loss were examined. Results: An anastomotic stricture was found in 18 cases (6%) requiring some kind of treatment. In 10 patients (56%), the bladder neck stricture occurred within 3 months after surgery, in 5 (28%) at 4–12 months after surgery and in 3 (16%) more than 12 months after surgery. Intraoperative blood loss (>1,000 ml) was found to be significantly correlated with urinary leakage (p < 0.001) and both correlated with anastomotic stricture formation (p < 0.005). Conclusion: Excessive intraoperative blood loss (>1,000 ml) and urine leakage was found to be significantly correlated to the formation of anastomotic stricture following radical retropubic prostatectomy.

The purpose of this study was to investigate the effects of radical prostatectomy (RP) for prostate cancer, transurethral resection of the prostate (TURP) for benign prostate hyperplasia (BPH), and the alterations induced by ageing on quality of life, urinary and sexual function, and bother. We evaluated 283 patients who filled in and returned the questionnaire used. A total of 105 were treated with RP and were selected prostate cancer patients with localised disease without recurrences. An additional 98 underwent TURP for BPH and a third group consisted of 80 apparently healthy men. The general quality of life was estimated by the Rand 36-Item Health Survey 1.0. Urinary function was estimated by the AUA Symptom Index and the UCLA Prostate Cancer Index (urinary function and bother scale). Sexual function and bother, were explored using the Brief Male Sexual Function Inventory for Urology. Patient outcome 2 years post treatment was compared to the pre-treatment status and to that of the matched control population. General quality of life was not affected by RP or TURP, with the exception of an increase in the emotional/well being domain in RP patients to control group levels. After RP there was more bother reported for the urinary function than urinary malfunction itself, while TURP, as expected, restored urinary function and bother to normal population norms. Elderly males had urinary function and bother similar to the operated patients. Estimating sexual function on RP patients, erectile dysfunction (ED) predominates, leading to decreased sexual life. TURP marginally affects sexual life, mainly due to the loss of ejaculation, while in men from the control group, sexual function, although affected, was still present.
