Combination of Perianal-Intrarectal Lidocaine-Prilocaine Cream and Periprostatic Nerve Block for Pain Control During Transrectal Ultrasound Guided Prostate Biopsy: A Randomized, Controlled Trial

PURPOSEnTo our knowledge the optimal analgesia during prostate biopsy remains undetermined. We tested the efficacy and safety of combined perianal-intrarectal lidocaine-prilocaine cream and periprostatic nerve block during transrectal ultrasound guided prostate biopsy.nnnMATERIALS AND METHODSnA total of 280 patients were randomized to receive combined perianal-intrarectal lidocaine-prilocaine cream and periprostatic nerve block (group 1), perianal-intrarectal lidocaine-prilocaine cream alone (group 2), periprostatic nerve block alone (group 3) or no anesthesia (group 4) before transrectal ultrasound guided prostate biopsy. Pain was evaluated with a 10-point visual analog scale at subsequent procedural steps, including perianal-intrarectal substance administration, prostate transrectal ultrasound, periprostatic nerve block and sampling. Complications were assessed by self-administered questionnaire and telephone interview.nnnRESULTSnThe groups were comparable in patient age, prostate volume, pathology results and visual analog scale perianal-intrarectal substance administration. Visual analog scale results for transrectal ultrasound were lower in groups 1 and 2 vs 3 and 4 (mean 1.5 and 1.41 vs 5.37 and 5.31, p <0.001) and results for periprostatic nerve block were lower in group 1 vs 3 (mean 1.03 vs 3.74, p <0.001). Results for sampling were lower in groups 1 to 3 vs 4 (mean 0.77, 1.27 and 1.27 vs 4.33, p <0.001) and in group 1 vs 2 and 3 (p <0.001). Stratified analysis showed that visual analog scale sampling was lower in group 1 vs 2 and 3 in patients 65 years old or younger, those with a prostate greater than 49 cc and those with lower anorectal compliance (visual analog scale results for perianal-intrarectal substance administration greater than 2) (p = 0.006, <0.001 and 0.003, respectively). The overall complication rate was similar in all 4 groups (p = 0.87).nnnCONCLUSIONSnOur findings suggest that the combination of perianal-intrarectal lidocaine-prilocaine cream and periprostatic nerve block provides better pain control than the 2 modalities alone during the sampling part of transrectal ultrasound guided prostate biopsy with no increase in the complication rate. The magnitude of this effect is higher in younger men, men with a larger prostate and men with lower anorectal compliance.

The Italian Linguistic Validation of the Ureteral Stent Symptoms Questionnaire

PURPOSEnWe validated the Italian version of the Ureteral Stent Symptoms Questionnaire in male and female patients with an indwelling ureteral stent.nnnMATERIALS AND METHODSnA double-back translation of the original Ureteral Stent Symptoms Questionnaire was performed by 3 urologists and 4 professional translators. A total of 78 patients (cases) with and 35 healthy subjects without (controls) an indwelling ureteral stent were asked to complete the Italian version of the Ureteral Stent Symptoms Questionnaire and a visual analog scale for pain as well as the International Prostate Symptom Score (men) and Urogenital Distress Inventory-6 plus Incontinence Impact Questionnaire-7 (women). Cases were evaluated at weeks 1 and 4 after stent placement, and at week 4 after removal, while controls were evaluated once. The psychometric properties of the questionnaire were analyzed.nnnRESULTSnA total of 66 cases and 30 controls were suitable for analysis. The questionnaire showed good internal consistency in all domains except global quality of life compared with that of the International Prostate Symptom Score (Cronbachs alpha >0.75). Test-retest reliability was good except for the sexual matters domain (Pearsons coefficient >0.7). Relatively high correlation coefficients (greater than 0.65) were found for the visual analog scale for pain, the International Prostate Symptom Score, the Urogenital Distress Inventory-6 and the Incontinence Impact Questionnaire-7 with the corresponding Ureteral Stent Symptoms Questionnaire domains, suggesting good convergent validity. Sensitivity to change and discriminant validity were also good (p <0.001).nnnCONCLUSIONSnThe Italian version of the Ureteral Stent Symptoms Questionnaire is a reliable and robust instrument that can be self-administered to male and female Italian patients with an indwelling ureteral stent in the clinical and research settings.

Prulifloxacin versus levofloxacin in the treatment of chronic bacterial prostatitis: a prospective, randomized, double-blind trial.

Abstract Ninety-six patients with chronic bacterial prostatitis (CBP) and evidence of infection were randomized to receive a 4-week oral course of either prulifloxacin (a new fluoroquinolone) 600 mg or levofloxacin 500 mg once daily. They were evaluated with the Meares-Stamey test and the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) at baseline and one week after therapy completion. Patients with microbiological eradication were evaluated again with the Meares-Stamey test 6 months after therapy completion. The microbiological eradication rate was 72.73% for prulifloxacin and 71.11% for levofloxacin (p=0.86) and the reduction in the NIH-CPSI was 10.75 and 10.73, respectively (p=0.98). Safety was comparable, with 18.18% adverse events for prulifloxacin and 22.22% for levofloxacin (p=0.79). Thus, a 4-week course of prulifloxacin 600 mg once daily is at least as effective and safe as levofloxacin 500 mg once daily in the treatment of CBP.

Orgasm-Associated Incontinence (Climacturia) after Bladder Neck-Sparing Radical Prostatectomy: Clinical and Video-Urodynamic Evaluation

INTRODUCTIONnOrgasm-Associated Incontinence (OAI) or climacturia has been observed in male patients maintaining sexual potency after radical prostatectomy and cystectomy.nnnAIMnWe investigated the incidence and video-urodynamic aspects of this event in continent and potent patients after bladder neck-sparing (BNS) radical prostatectomy (RP).nnnMAIN OUTCOME MEASUREnComparing functional and morphological aspects between climacturic and non-climacturic patients to identify a possible explanation of this unusual kind of leakage that could seriously impact the sexual life after surgery.nnnMETHODSnIn a pool of 84 men, potent and continent at least 1 year after BNS RP, 24 (28.6%) reported climacturia and 7 agreed to undergo video-urodynamic evaluation (group 1), which was performed also in 5 controls (group 2). Those 12 men were also evaluated with 24-hour pad test, 5-item International Index of Erectile Function and International Prostate Symptom Score questionnaires.nnnRESULTSnFunctional urethral length (FUL) was significantly lower in the climacturia group (P=0.02) and time to continence recovery was significantly longer (P=0.05). No other significant differences were found between the two groups. The radiological appearance of the vesicourethral junction at voiding cystourethrography was similar.nnnCONCLUSIONSnTo the best of our knowledge, this is the first functional and morphological evaluation of climacturia after RP. In our experience, this event is indirectly associated with a reduced FUL in the sphincter area, although both patients and controls were continent during daily activities. BNS technique seems to reduce time to continence recovery, although climacturic patients need longer time than control patients. Since in our series no rigidity of the vesicourethral anastomosis was radiographically evident, we believe that differences in FUL could explain OAI. Anatomical difference in membranous urethra length could explain the occurrence of this symptom in patients treated with the same surgical technique.

Renal cell carcinoma with caval involvement: Contemporary strategies of surgical treatment

OBJECTIVESnWe retrospectively evaluated the outcome of the surgical treatment of patients with renal cell carcinoma (RCC) and extensive inferior vena cava (IVC) involvement. Our aim was to investigate if a particular surgical technique could reduce morbidity and complications associated with this condition.nnnMATERIALS AND METHODSnFrom 1996 to 2007, 22 patients with RCC and extensive IVC involvement underwent radical surgical treatment with the intention to avoid, whenever possible, sternotomy and cardiopulmonary bypass. The level of the tumor thrombus was I (<2 cm above the renal vein) in 2 patients, II (below the intrahepatic vena cava) in 9 patients, III (intrahepatic vena cava below the diaphragm) in 7 patients, and IV (atrial) in 4 patients. Extracorporeal vascular bypass was used for 4 patients with level IV and for 2 patients with level III tumor thrombi, with hypothermic circulatory arrest in 2 patients. Extensive liver mobilization techniques were adopted in 16 patients. Overall and cancer-specific survival (CSS) were analyzed based on tumor extent (N0M0, N+M+), pathologic stage (pT3b, pT3c, pT4), thrombus level, and caval wall infiltration.nnnRESULTSnTwo patients died within 1 month of surgery and the remaining 20 patients have a mean follow-up of 32.2 months (range 6-90): 8 are alive (overall survival 40%), but 2 with disease (CSS 30%). A total of 10 severe complications developed in 8 patients (36%). Both overall and CSS were significantly associated with tumor stage (Log-rank P = 0.0237 and 0.0465), presence of nodal or systemic metastases (Log-rank P = 0.0835 and 0.0669; Wilcoxons test P = 0.0407 and 0.0411), and caval wall infiltration (Log-rank P = 0.0200 and 0.0418).nnnCONCLUSIONSnDespite the low overall survival, related to the high percentage of nodal and systemic metastases, aggressive surgical management with resection of synchronous metastatic disease for symptom palliation and cytoreduction, followed by immunotherapy is justified in this setting. A transabdominal approach to RCC and IVC involvement, even in patients with level III thrombus, can provide the surgeon with an exposure similar to thoracoabdominal incisions without the complications associated with thoracotomy.

Testis-sparing surgery for benign and malignant tumors: A critical analysis of the literature.

In order to explore the latest advances in organ-sparing treatment of testicular tumors, a literature search of the Medline/PubMed database was carried out for published data in the English language up to 2007. In the recent past the management of testicular tumors has evolved in favor of a testis-sparing approach in selected cases, both in the adult and pediatric population. The widespread use of high-frequency testicular ultrasound has led to detecting an increasing number of asymptomatic, non-palpable, small-volume masses. A higher proportion of testicular lesions of benign nature than previously reported has now been documented. The high accuracy of frozen section examination and the increasing interest in the potential functional, psychological and cosmetic advantages related to preserved testicular parenchyma are other arguments currently favoring the adoption of an organ-sparing policy for most testicular masses. Greater experience has been gained in also managing conservatively malignant tumors. Patients with germ-cell cancer in solitary testis or bilateral tumors can be submitted to testis-sparing surgery, provided that the maximum size of the lesion is <2 cm, preoperative testosterone is normal and adjuvant radiotherapy of the residual parenchyma is delivered. Cancer-specific survival is excellent, local recurrence rate very low and androgen supplementation unlikely.

Orthotopic bladder substitute in renal transplant recipients: experience with Studer technique and literature review.

Renal transplant recipients with high‐risk bladder cancer following cystectomy need a urinary diversion preserving the renal function and possibly maintaining body image, while still offering the best oncological outcome. The aim of this report is to describe our experience of radical cystectomy and orthotopic ileal neobladder with Studer technique in this population, and to review the literature. We performed radical cystectomy and Studer ileal neobladder in four male patients (median age 67u2003years) after median time of 9.5u2003years following renal transplantation. Pathology revealed pT1HGN+ transitional cell carcinoma in one case, pT1HGN0 in two and pT3aHGN0 in one. Two patients presenting aggressive disease (N+ and pT3a) died of tumour progression after 20 and 14u2003months, respectively, while the other two are alive after 56 and 36u2003months of follow‐up with no evidence of disease, stable serum creatinine (2.29 and 1.6u2003mg/dl) and mild metabolic acidosis. Day and night‐time urinary continence were satisfactory in all patients. Good functional outcomes have been reported in the 20 cases of ileal orthotopic neobladder with different techniques published so far and the global experience of 24 cases with a median follow‐up of 39u2003months documents a cancer specific survival of 62.5%.

To compare the efficacy of periprostatic nerve block (PNB) alone vs PNB combined with the local administration of a 1.5% lidocaine/0.3% nifedipine cream (Antrolin®, Bracco, Milan, Italy).

Value of image fusion in the staging of prostatic carcinoma.

Purpose.We assessed the value of image fusion in the staging of prostatic cancer in a series of 32 patients who underwent preoperative evaluation with transrectal colour-Doppler ultrasonography (TRUS) and magnetic resonance imaging (MRI).Materials and methods.Colour-Doppler TRUS exams were performed using a 7.5-MHz biplanar probe. MRI exams were done with a scanner operating at 1.5 Tesla (T) using an endorectal coil. All patients underwent radical prostatectomy within 2 weeks from the imaging assessment. Whole-mount sections were prepared from the surgical specimens and were subsequently digitised by using a high-resolution scanner. The Digital Imaging and Communications in Medicine (DICOM) TRUS and MR images as well as the digitised pathological images were transferred to a graphic workstation to perform image fusion.Results.Image fusion was technically possible in 25/32 cases in which axial TRUS images were available. The following fusion images were obtained: TRUS + pathological sections; MRI + pathological sections; TRUS + MRI + pathological sections. The final pathological staging concerning the T status was: four pT2b, fourteen pT2c, three pT3a and four pT3b. The three types of image fusion led to the following results: TRUS + pathological sections, correct staging in 20/25 cases (accuracy 80%); MRI + pathological sections, correct staging in 22/25 cases (accuracy 88%); TRUS + MRI + pathological sections, correct staging in 23/25 cases (accuracy 92%).Conclusions.Our study suggests that by using image fusion between colour-Doppler TRUS and endorectal MRI, it is possible to improve the accuracy of pathological staging in patients who are candidates for radical prostatectomy.

Radical Prostatectomy, Sparing of the Seminal Vesicles, and Painful Orgasm

INTRODUCTIONnErectile dysfunction has been widely investigated as the major factor responsible for sexual bother in patients after radical prostatectomy (RP); painful orgasm (PO) is one element of this bother, but little is known about its prevalence and its effects on sexual health.nnnAIMnThis study aims to investigate the prevalence of PO and to identify potential risk factors.nnnMAIN OUTCOME MEASURESnA total of 1,411 consecutive patients underwent open (radical retropubic prostatectomy) or robot-assisted laparoscopic RP between 2002 and 2006. The patients were asked to complete a study-specific questionnaire.nnnMETHODSnOf a total of 145 questions, 5 dealt with the orgasmic characteristics. The questionnaire was also administered to a comparison group of 442 persons, matched for age and area of residency.nnnRESULTSnThe response rate was 91% (1,288 patients). A total of 143 (11%) patients reported PO. Among the 834 men being able to have an orgasm, the prevalence was 18% vs. 6% in the comparison group (relative risk [RR] 2.8, 95% confidence interval [CI] 1.7-4.5). When analyzed as independent variables, bilateral seminal vesicle (SV)-sparing approach (RR 2.33, 95% CI 1.0-5.3, Pu2009=u20090.045) and age <60 years were significantly related to the presence of PO (95% CI 0.5-0.9, Pu2009=u20090.019). After adjustment for age, bilateral SV-sparing still remained a significant predictor for occurrence of PO.nnnCONCLUSIONSnWe found that PO occurs significantly more often in patients undergoing bilateral SV-sparing RP when compared with age-matched comparison population.
