Simultaneous curvature correction at the time of the penile fracture repair: surgical and functional outcomes.

Purpose: After a penile fracture (PF), an early surgical exploration and defect closure of the lesions are recommended to prevent long-term complications. However, postoperative unsatisfactory penile curvatures are frequent in the literature. In this study, we wished to present surgical outcomes of PF after surgical repair approach with an early intraoperative curvature correction and update our series with postoperative follow-up. Patients and methods: An institutional retrospective review study of 36 patients undergoing surgical treatment for PF was performed. Mean age of patients was 53.2 years. All surgical explorations were performed within 12 hours after the traumatic event. The surgical repair with a contemporary penile plication was then made to straighten the tunica angulations in patients with curvature greater than 30°, using 2- 3 pairs of 2-0 absorbable suture of polydioxanone. Results: The length of the tear ranged from 8 to 20 mm. 77.7% of the patients required a correction of the cavernous body deviation. No early complications occurred in any case. The median patient stays in the hospital was 3.4 days. At a mean follow-up of 20.6 months, all patients were able to insert the penis in the partner's vagina, and were satisfied overall with sexual intercourse; three patients (10.7%) reported residual pain and discomfort for the knots of the sutures. Conclusions: An early intraoperative curvature correction may be used for a variety of angulation deformities and severe degrees of deviations secondary to a repair after penile trauma, and may be helpful in preventing postoperative morbidity.

May ultrasound probe size influence pain perception of needle piercing during transrectal prostate biopsy? A prospective evaluation.

INTRODUCTION AND OBJECTIVE: Transrectal ultrasound guided prostate biopsy (TRUS-Bx) is the definitive step in the diagnosis of prostate cancer (CaP). Patients (pts) generally experience significant pain during the procedure at the point that biopsy should be accompanied by some form of anesthesia. Several different factors influence pain perception (PP) during TRUS-Bx. In our study we want to assess that the use of an ergonomic smaller sized probe reduces PP during the procedure independently from the administration of local anesthesia or pain relieving drugs. MATERIALS AND METHODS: This was a prospective, randomized study in which 114 pts who underwent TRUS-Bx due to abnormal PSA and/or to digital rectal examination (DRE) suspicious findings were considered eligible. Pts were split in two TRUS-Bx groups into which we used two different sized ultrasound probes. In group 1, 61 pts underwent TRUS-Bx with ALOKA end fire probe (size 74 mm). In group 2, 53 pts underwent TRUS-Bx with B-K Type 8818 probe (size 58 mm). Both groups were treated with no local anesthesia or pain relieving drugs. Pain was evaluated three times using a 10-point visual analogue scale (VAS), during the DRE (VAS 1), during the insertion of the probe (VAS 2) and during the needle piercing (VAS 3). RESULTS: Mean age of pts was 68.03 (SD 8.51); mean tPSA and mean prostate volume was 7.75 (SD 4.83) and 45.17cc (SD 17.7), respectively. The two groups were homogeneous respect to tPSA (p = 0.675) and to prostate volume (p = 0.296); age was significantly different (p = 0.04) between Group 1 (65.93) and Group 2 (70.43), whereas no statistically significant correlation between VAS 3 and age was observed (p = 0.179). Analyzing pain perception, we found no statistically significant difference between the two groups in DRE (VAS 1; p = 0.839); on the contrary, patients in Group 1 experienced on average more pain than other in Group 2 both during the insertion of the probe (VAS 2 3.49 vs 1.09; p < 0.001) and during the needle piercing VAS 3 (2.8 vs 2.00; p < 0.05). The discomfort during probe insertion and manipulation was perceived as very high (VAS 2 > 5) in 42.6% of patients in Group 1 and in 9.4% in Group 2. Globally, the procedure was well tolerated (mean VAS score < 3) in 77% of patients in Group 1 and in 90% in Group 2. The proportion of patients who experienced more than moderate pain (VAS > 5) during needle piercing ranged 24.6 % in Group 1 to 18.9 % in Group 2. CONCLUSIONS: Patients who underwent a TRUS-Bx with the 58-mm circumference probe were found to experience lower degree of pain not only during the insertion of the probe through the anal sphincter, but also in the moment of needle piercing.

Safety and efficacy of percutaneous nephrolithotomy in the Galdakao - Modified Supine Valdivia position: A prospective analysis.

OBJECTIVE: Aim of the present study was to evaluate the safety and efficacy of Percutaneous Nephrolithotomy (PCNL) in the Galdakao- Modified Supine Valdivia (GMSV) position in order to predict operative time, stone-free rate and onset of complications taking into account comorbidity, stone-related parameters and anatomic upper urinary tract abnormalities. MATERIAL AND METHODS: A prospective evaluation of patients who underwent to PCNL in GMSV position for renal stones > 2 cm, from January 2009 to February 2015 was performed. According to the technique, upper urinary tract abnormalities, stone chemical and morphological characteristics, and patients' history were matched with operative outcome, in terms of stone-free, intervention time and incidence of perioperative complications. RESULTS: Seventy-two cases were collected; mean operative time was 105 minutes (DS 41): staghorn stones and the presence of comorbidity resulted statistically significant variables. The complication-rate resulted in line with data showed in literature: hyperpyrexia and hemorrhage were the more frequently complications found. The overall stone-free was reached in 48 patients (67%), and it was influenced by patients' anatomic abnormalities. CONCLUSIONS: In the treatment of renal stones, PCNL may be a safe and effective choice; nevertheless, patients' anatomic abnormalities or staghorn-stones may influence the outcomes. Thus, a prospective study with a larger population is needed to verify our outcomes.

Cognitive zonal fusion biopsy of the prostate: Original technique between target and saturation.

We describe our experience in prostate biopsy using a new standardized cognitive fusion techniques, that we call "cognitive zonal fusion biopsy". This new technique is based on two operative options: the first based on target biopsies, the Cognitive Target Biopsy (CTB) if the same target was detected with transrectal ultrasound (TRUS) and multiparametric magnetic resonance (mpMRI); the second based on saturation biopsies, the Zonal Saturation Biopsy (ZSB) on anatomical zone/s containing the region of interest if the same target was not evident with TRUS and MRI. We evaluated results of our technique compared to standard biopsy in order to identify clinically relevant prostate cancer. METHODS: This is a single-center prospective study conducted in 58 pts: 25 biopsy-naïve, 25 with previous negative biopsy and in 8 with cancer in active surveillance. Based on mpMRI and transrectal ultrasonography (TRUS), all patients were scheduled for standard 12-core TRUS-guided biopsy. If mpMRI was suggestive or positive (PI-RADS 3, 4 or 5): patients underwent additional targeted 2 to 6 cores using cognitive zonal fusion technique. RESULTS: 31/58 (53.4%) patients had a cancer. Our technique detected 80.6% (25 of 31) with clinically significant prostate cancer, leading to detection of insignificant cancer in 20%. Using standard mapping in MR negative areas we found 5 clinically significant cancer and 4 not significant cancers. MRI cancer detection rate was 18/31 (58.1%), and 9/18 (50%) in high grade tumors. Therefore MRI missed 50% of high grade cancers. The mean number of cores taken with cognitive zonal fusion biopsy was 6.1 (2-17), in addition biopsy sampling was done outside the ROI areas. Overall 15.4 cores (12-22) were taken. Cancer amount in Zonal Biopsy was larger than 7.3 mm (1-54.5) in comparison with 5.2 mm (1-23.5) in standard mapping. Largest percentage of cancer involvement with cognitive zonal fusion technique was detected in 19.4% vs 15.9%. CONCLUSIONS: Cognitive Zonal Saturation Biopsies should be used to reduce operator variability of cognitive fusion biopsy in addition to standard biopsy. Cognitive zonal biopsy based on mpMRI findings identifies clinically relevant prostate in 80%, has larger cancer extension in fusion biopsies than in random biopsies, and reduce the number of cores if compared to saturation biopsy.

Diagnostic and therapeutic utility of transrectal ultrasound in urological office prostatic abscess management: a short report from a single urologic center.

OBJECTIVES: Prostatic abscess (PA) is an infrequent condition in the modern antibiotic era. The everyday use of transrectal ultrasound (TRUS) during diagnostic work-up and the widespread recurrence to prostatic biopsies may lead to an increase of PA diagnosis. In this short report we analyze the patients characteristics and the management of seven recent cases of PA diagnosed in our institution. MATERIALS AND METHODS: The records of 7 patients admitted to our Center for LUTS associated to septic fever or acute urinary retention, was prospectively collected. Suspect of PA was done on digital rectal examination (DRE) and confirmed by TRUS performed after urinary system ultrasound (UUS) evaluation. Patients were admitted to hospital only in case of septic signs. A sovrapubic (SPC) or urethral catheter (UC) was placed depending on symptoms. A TRUS-guided aspiration of PA was performed with patient in lithotomic position, using a 18 gauge two-part needle, side/end fire needle access. Patient was discharged with antibiotic therapy and followed up until complete resolution of the PA and symptoms. RESULTS: Mean age was 62 years (range 24-82). Two patients were diabetics and one was affected by the immunodeficiency acquired syndrome (HIV). In one case, PA was detected after a persistent fever post TRUS guided prostate biopsy. Average prostate volume was 69 ml (range 19-118 ml). DRE was able to diagnose PA only in 2 cases (29%), UUS evaluation in 1 case (14%). All cases were confirmed by TRUS as hypo-anechoic areas with or without internal echoes in all patients. Mean PA dimension was 3.64 cm (range 1.5-8). SPC was placed in 3 cases (43%), UC in 3 patients (43%). Only 1 patient refused catheterization. Side fire needle aspiration was performed in all cases and in combination with end fire access in case of particular location of abscess cavities. Second look was needed in 2 cases (29%). Antibiotics were administered in all cases. The aspirated pus showed a positive culture for Escherichia coli (43%), Klebsiella pneumoniae (29%), Pseudomonas aeruginosa (14%) and Enterococcus faecalis (14%). PA resolution time mean was 9 days (range 3-24). CONCLUSIONS: TRUS evaluation in case of persistent LUTS associated with fever or acute urinary retention is determinant in the diagnosis of PA. Office or institutional management with TRUS needle aspiration is a good option in these cases.

Diagnostic ultrasound-guided excisional testicular biopsy for small (< 1 cm) incidental nodules. A single institution experience.

INTRODUCTION AND OBJECTIVES: The widespread use of scrotal ultrasound (SUS) has led to a marked increase in the number of incidentally detected testicular lesions. A small incidental nodule (STN) has defined as a non palpable (< 10 mm), asymptomatic solid lesion with normal levels of oncological testicular markers. Nowadays the lack of agreement on the topic causes managing problems to andrologists. We present our experience consisting in 8 cases of STN discovered by SUS performed for different clinical indications. MATHERIAL AND METHODS: We retrieved from our ultrasonographic files the clinical information about 717 patients evaluated for andrological problems. Patients with STN underwent to a complete clinical history and physical examination as well as oncological testicular markers measurement and ormonal assessment and then received a diagnostic ultrasound guided excisional biopsy (DEB). Surgical approach was performed through an inguinal incision. Using the coordinates previously obtained from preoperative SUS, STN was localized by intraoperative SUS. The lesion was enucleated and sent to the Pathology department for frozen section examination (FSE). Biopsies of affected testis (TB) were also performed. Post-excision ultrasound has been used to confirm the complete removal of the nodule. Whether pathological findings were benign, testis sparing surgery (TSS) was performed. Immediate radical orchidectomy (IRO) was performed if FSE and TB findings suggested a malignant lesion. RESULTS: STNs were discovered in 8 patients (1,1%). Very small lesions (< 5 mm) were detected in 50% of cases. We performed four IRO and four DEB with consequent TSS. In one case we performed a delayed radical orchidectomy (DRO). At FSE pathologist reported 3 Leydig cell tumor and 3 seminoma and an inflammatory regressive lesion in one case. FSE on TB reported intratesticular neoplasia (TIN) in three cases. In one case nodule wasn't sent to FSE. We observed a concordance between FSE and definitive pathologic report in six cases (75%). CONCLUSIONS: The management of STN is still a challenge for the surgical andrologist. A correct diagnosis has a crucial role in making the best treatment and patients outcome. Ultrasound guided excisional biopsy and the close collaboration with a dedicated pathologist are very useful in reducing errors.
