Impact of Minimally Invasive Benign Prostatic Hyperplasia Therapies on 30- and 90-Day Postoperative Office Encounters.

OBJECTIVE: To compare the frequency of postoperative encounters in the 30-day and 90-day postoperative periods for various bladder outlet obstruction surgical therapies. MATERIALS AND METHODS: All patients who underwent transurethral resection of the prostate (TURP), GreenLight laser photovaporization of the prostate (GL-PVP) (American Medical Systems Inc.), and holmium laser enucleation of the prostate (HoLEP) from January 1, 2012 to December 31, 2014 were followed for 6 months postoperatively. All postoperative encounters such as patient calls or questions, catheter exchanges or removals, and hospital-based readmissions or emergency department visits were recorded in the electronic medical record. RESULTS: Two hundred and ninety-one consecutive patients underwent outlet procedures during the study period: TURP (N = 199; mean age, 71 years; mean body mass index [BMI], 28.5), HoLEP (N = 60; mean age, 68 years; mean BMI, 28.1), or GL-PVP (N = 32; mean age, 72 years; mean BMI, 29.3). No statistically significant difference was observed for age, BMI, preoperative American Urological Association symptom score, or preoperative maximum flow velocity between the 3 groups. Thirty-day postoperative encounters differed significantly between the 3 surgery types (P < .001). Specifically, there were fewer encounters within 30 days of surgery for TURP compared to both HoLEP (≥1 encounter: TURP = 48.7%, HoLEP = 66.7%; P = .006) and GL-PVP (≥1 encounter: TURP = 48.7%, GL-PVP = 93.7%; P < .001). The number of encounters within 90 days postoperatively was also significantly lower for TURP patients (P < .001). CONCLUSION: TURP results in fewer postoperative encounters in both the 30-day and 90-day postoperative periods compared to HoLEP and GL-PVP. Laser prostate therapies may place increased burden on clinic staff during the 30-day and 90-day postoperative periods.

Urologic-Induced Complications of Prophylactic Ureteral Localization Stent Placement for Colorectal Surgery Cases.

PURPOSE: A prophylactic ureteral localization stent (PULSe) placed by urologists aids in intraoperative localization and detection of suspected ureteral injury during complex colorectal surgery (CRS) cases. We evaluated the incidence and management of urologic-induced complications secondary to PULSe placement during CRS cases at a single center. MATERIALS AND METHODS: We performed a retrospective review of all patients who underwent cystoscopy and PULSe placement at the time of CRS over a 12-month period. Bilateral 5 French ×70-cm TigerTail® (Bard Medical Division, Covington, GA) PULSe devices were placed without assistance of routine fluoroscopy. RESULTS: Ninety-nine patients (mean age, 58.1 years; range, 17-88 years) underwent bilateral PULSe placement, with a male:female ratio of 44:55 and a mean body mass index of 26.8 (17.0-38.6) kg/m(2). Mean pre- and postprocedural creatinine levels were 0.91 and 1.01 mg/dL, respectively. Twenty-two of 99 (22%) cases utilized a guidewire to aid in placement of PULSe. Four Clavien grade IIIb complications occurred: mucosal edema, reflex anuria, ureteral perforation, and ureteral obstruction secondary to significant clot burden. Three of the grade IIIb complications were managed endoscopically with double-J stent placement. The ureteral perforation case required percutaneous nephrostomy tube placement. Subgroup analysis of the four grade IIIb complications revealed a mean age of 62.3 years, body mass index of 26.98 kg/m(2), and pre- and postprocedural creatinine levels of 0.95 and 4.83 mg/dL, respectively. Only one of the four grade IIIb complications utilized a guidewire prior to PULSe placement. CONCLUSIONS: The incidence of Clavien grade III urologic-induced complications during PULSe placement is approximately 2% (4/188). Mandatory adoption of fluoroscopy and guidewires may be required to minimize complications of PULSe placement.

Characterization of ureteral stents by dual-energy computed tomography: Clinical implications.

Dual-energy computed-tomography (DECT) has been suggested as the method of choice for imaging urinary calculi due to the modality's high sensitivity for detecting stones and its capability of accurately differentiating between uric-acid (UA) and non-UA (predominantly calcium) stones. The clinical significance of the latter feature relates to the differences in management of UA vs non-UA calculi. Like calculi, ureteral stents are assigned color by the dual-energy post-processing algorithm, which may lead to improved or worsened stone visualization based on the resulting stent/stone contrast. Herein we depict the case of a nephrolithiasis patient with bilateral stents, each with different color, clearly displaying the effect of stent color on stone visualization. Further, three-dimensional reconstruction of the DECT images illustrates advantages of this enhancement compared to conventional two-dimensional computed tomography. The resulting stent/stone contrast produces an unanticipated potential advantage of DECT in patients with urolithiasis and stents and may promote improved management decision-making.

Three-dimensional dual-energy computed tomography for enhancing stone/stent contrasting and stone visualization in urolithiasis.

The use of dual-energy computed tomography (DECT) for evaluating urinary calculi has been appreciated due to the modality's capability of differentiating between uric acid (UA) and non-UA stones, which are color coded based on a postprocessing algorithm. No other imaging modality or laboratory test is able to identify the stone composition without first attaining the stone material. Knowledge of the stone composition is clinically significant since UA calculi may be treated medically whereas non-UA calculi may require surgical removal. Regardless of the stone type, ureteral stents are often placed to prevent or treat obstruction. Recent work has demonstrated that commonly used stents are also colored based on their dual energy characteristics and may thereby either improve or obscure the identification of adjacent calculi. Herein, we report the case of a 65-year-old man who underwent percutaneous nephrolithotomy of a large staghorn stone with subsequent significant residual stone fragments noted on a follow-up scan. By using three-dimensional DECT and taking advantage of color contrasting, the stone composition, burden, shape, and boundary were clearly depicted apart from the adjacent stent, resulting in successful medical treatment and obviating the need for further surgical intervention.

Effect of leuprolide on serum amyloid-ß peptide levels and memory in patients with prostate cancer with biochemical recurrence.

OBJECTIVE: To investigate whether prostate cancer patients receiving leuprolide demonstrated objective cognitive decline accompanied by a change in plasma levels of amyloid-ß. METHODS: Between November 19, 2003, and July 21, 2008, we prospectively enrolled 50 patients with biochemical recurrence of prostate cancer and measured plasma amyloid-ß peptide 40 and amyloid-ß peptide 42 levels with sandwich enzyme-linked immunosorbent assay at baseline before the first leuprolide injection and at 2, 4, and 12 months. The Mini-Mental State Examination was used to assess 49 patients at baseline and at subsequent visits, and 24 were also assessed by the California Verbal Learning Test-Short Form. RESULTS: Patients were a median age of 71 years (range, 59-89 years). Compared with baseline levels, plasma amyloid-ß peptide 40 levels were increased at 2 months (P=.04) and 4 months (P=.02). Age was correlated with plasma amyloid-ß peptide 40 levels (P=.003) and likely accounted for this relationship. Plasma amyloid-ß peptide 42 and performance on cognitive tasks did not differ from baseline, but memory measures improved slightly after baseline, most likely due to a practice effect. CONCLUSION: Leuprolide therapy was not associated with a decline in cognition or memory function or with elevated plasma amyloid short-term. Larger studies are needed to confirm these findings.

Robotic-assisted bladder diverticulectomy: tips and tricks.

INTRODUCTION: The da Vinci Surgical System has become extremely popular in the field of urology for procedures requiring complex reconstructive maneuvers, such as radical prostatectomy and pyeloplasty. A natural extension of these procedures is the use of the da Vinci system for complex urinary tract reconstruction deep in the pelvis, such as bladder diverticulectomy. TECHNICAL CONSIDERATIONS: In our report and accompanying Video, we have demonstrated some technical tips and tricks with regard to patient selection, preoperative imaging, patient positioning, port placement, intraoperative diverticulum recognition/excision, and cystotomy repair that the surgeon might find beneficial for successful completion of robotic-assisted bladder diverticulectomy. CONCLUSIONS: The tips and tricks we have presented might aid in the successful completion of robotic bladder diverticulectomy.

Evaluation of pancreatic damage after extracorporeal shock wave lithotripsy, percutaneous stone surgery, and ureteroscopy.

OBJECTIVES: To complete a prospective evaluation of serum amylase and lipase levels before and after shock wave lithotripsy (SWL) for renal stones. We also compared these serum levels to those of patients undergoing percutaneous and ureteroscopic stone surgery. SWL injury to the pancreas should be noted by an increase in serum amylase and lipase. METHODS: A prospective evaluation of 38 patients (16 who underwent SWL, 15 who underwent percutaneous nephrostolithotomy, and 7 who underwent ureteroscopic stone manipulation) who underwent treatment of renal calculi at our institution was completed. The control group was the combined group of patients who had undergone percutaneous nephrostolithotomy or ureteroscopic stone manipulation. The serum amylase and lipase levels were measured before the procedure, immediately after the procedure (2 hours), and ≥30 days after the procedure. RESULTS: No statistically significant difference was found in the change from before to immediately after the procedure between the SWL group and the controls in amylase (median decrease 6 U/L vs 11 U/L, P = .45) or lipase (median decrease 4 U/L vs 9 U/L, P = .31). Also, no statistically significant evidence was seen in the change from before to >30 days after the procedure between the SWL group and controls in the amylase level (median increase 0 U/L vs 2 U/L, P = 1.00) or lipase (median change 2 U/L increase vs 1 U/L decrease, P = .96). CONCLUSIONS: SWL does not appear to noticeably increase the serum amylase and lipase level directly postoperatively or >30 days after the procedure compared with baseline or compared with the controls.

Safety and peri-operative outcomes during learning curve of robot-assisted laparoscopic prostatectomy: a multi-institutional study of fellowship-trained robotic surgeons versus experienced open radical prostatectomy surgeons incorporating robot-assisted laparoscopic prostatectomy.

PURPOSE: To analyze and compare the safety and peri-operative outcomes of fellowship-trained robotic surgeons (FEL) and experienced open surgeons (OE) incorporating robot-assisted laparoscopic prostatectomy (RALP) into practice. MATERIALS AND METHODS: Multiinstitutional, prospective data were collected on the first 30 RALP performed by FEL and OE (defined as over 1000 prostatectomies) incorporating RALP into practice. Morbidity from the peri-operative course was evaluated as were operative outcomes. The second 30 cases from the OE group were evaluated to assess for improvement with experience. RESULTS: There were no rectal injuries or death in either group. Blood transfusion rates did not differ between the two groups (2% vs. 3%, p = 0.65). Open conversion occurred three times in the OE group but only within the first 30 cases. In the first 30 cases FEL had statistically lower rates of positive margins (15% vs. 34%, p = 0.008) and decreased likelihood of prolonged urethral catheter leakage (5% vs. 19%, p = 0.009). The FEL group had lower rates of failure of prostate-specific antigen to nadir < 0.15 ng/mL (2% vs. 10%, p = 0.056). There were no reoperations in the FEL group but present in 2% of the OE group initially. The second 30 cases of the OE group noted a statistical improvement for all parameters with margin rates and the requirement of prolonged catheterization becoming statistically comparable to those of the FEL group. CONCLUSIONS: OE can safely incorporate RALP into practice and achieve outcomes comparable to FEL quickly. As anticipated, FEL achieve these endpoints earlier in their practice.

Paravertebral block provides significant opioid sparing after hand-assisted laparoscopic nephrectomy: an expanded case report of 30 patients.

PURPOSE: We report our experience of paravertebral block (PVB) on analgesic requirements and dynamic pain in patients presenting for hand-assisted laparoscopic nephrectomy (HALN) and compare our results with conventional opioid therapy. PATIENTS AND METHODS: From October 2006 to May 2008, 30 patients (male:female ratio, 17:13) scheduled for HALN received paravertebral analgesia preoperatively. Postoperative opioid requirements and dynamic visual analog scale pain scores were determined in the recovery room and every 8 hours for 48 hours postoperatively. Data were obtained from medical records and patient interview. RESULTS: The paravertebral analgesia was completed in all 30 patients with a mean visual analog scale score of 3.08 (0-10). Cumulative morphine equivalent doses were 11.82 mg (0-41 mg), whereas in two other studies, it ranged from 24 to 54 mg. CONCLUSION: PVBs provided excellent analgesia with significant opioid sparing in this pilot series of 30 patients with HALN. Utilization of multimodal analgesia incorporating PVB is recommended for patients presenting for HALN.

Late toxicity after postprostatectomy salvage radiation therapy.

PURPOSE: To evaluate late toxicity in patients who received salvage external beam radiotherapy (EBRT) for a detectable prostate-specific antigen (PSA) level after radical prostatectomy (RP). METHODS: A cohort of 308 consecutive patients underwent salvage EBRT from July 1987 through June 2003 for a detectable PSA level after RP. All were treated with high-energy photons (6-20 MV) to a median dose of 64.8 Gy (range: 54.0-72.4 Gy) in 1.8- to 2.0-Gy fractions. RESULTS: Median follow-up from the completion of EBRT was 60 months (range: 1 day-174 months). Late toxicity occurring more than 90 days after EBRT completion was identified in 41 patients (13%). Twelve patients (3.9%) had grade 2 urethral strictures and were treated with urethral dilation, 3 patients had grade 3 cystitis, and 1 had a grade 4 rectal complication. These numbers correspond to an estimated 0.7% (95% confidence interval, 0.0-1.6%) of patients experiencing a grade 3 or 4 complication by 5 years after the start of EBRT. CONCLUSIONS: Salvage EBRT for a detectable PSA level after RP is the only curative treatment in this setting. This treatment can be administered in a manner that results in a low likelihood of late complications.

Evaluation of the impact of body mass index on outcome among renal mass patients treated with hand-assisted laparoscopic radical nephrectomy.

PURPOSE: Although there are empiric data to show that obesity is not a contraindication for laparoscopic radical nephrectomy, similar data are lacking for the use of hand-assisted laparoscopic radical nephrectomy (HALRN) in obese patients. We evaluate whether obese patients undergoing HALRN to manage a renal mass are more likely than nonobese patients to experience poor intraoperative and perioperative outcomes. PATIENTS AND METHODS: Between June 1, 1999, and May 31, 2006, 150 patients underwent HALRN for the management of a solid renal mass at our institution. We abstracted detailed demographic, clinical, and follow-up data on all patients in this cohort. As our primary analysis, we evaluated associations between body mass index (BMI) and estimated blood loss, operative time, length of stay, and complications using linear and logistic regression models. RESULTS: There was no evidence that obese patients experienced a statistically significant or clinically relevant increase in blood loss (P = 0.97), operative times (P = 0.87) or length of stay (P = 0.62) compared with persons of normal weight. In contrast, although there was no evidence of a linear trend toward complications in patients with a higher BMI (P = 0.19), obese patients were almost three times more likely to experience a complication compared with normal-weight persons (odds ratio: 2.88; 95% confidence interval: 1.01-8.16). Adjusting for relevant clinical covariates individually did not markedly alter these associations. CONCLUSIONS: Obesity is not a contraindication for HALRN to manage a renal mass; however, obese patients should be aware that they may be at increased risk for certain complications after surgery, notably ileus and incisional hernias.

Do clinical or urodynamic parameters predict artificial urinary sphincter outcome in post-radical prostatectomy incontinence?

OBJECTIVES: To determine whether urodynamic or clinical parameters can predict artificial urinary sphincter (AUS) outcome in patients who were incontinent after radical prostatectomy (RP). Incontinence after RP is secondary to intrinsic sphincter deficiency, but urodynamics have been advocated before AUS placement to detect factors that could limit surgical success. METHODS: We reviewed all AUSs placed for RP incontinence from January 1995 to December 2004. The preoperative clinical parameters and urodynamic parameters were correlated with surgical success using linear and logistic regression analysis, respectively. Surgical failure was defined as requiring more than one pad per day. RESULTS: The data from 86 patients (mean age 72 years) were analyzed. Of these 86 patients, 15 (17%) were wearing more than 1 pad per day at the last follow-up visit; 11 patients (13%) considered their operation a failure; and 20 patients (24%) had postoperative urgency. The presence of detrusor overactivity (P = 0.92), low first sensation (P = 0.52), low bladder compliance (P = 0.38), and bladder capacity less than 300 mL (P = 0.58) in patients did not predict for AUS failure compared with patients without these findings. No clinical parameters were found that demonstrated a statistical association with the number of pads per day. Older patients considered themselves less improved (P = 0.012) than did younger patients. CONCLUSIONS: No evidence has shown that patients who are incontinent after RP who have detrusor overactivity, a low first sensation, decreased compliance, or a low bladder capacity have worse post-AUS outcomes than other patients. Older patients tended to have decreased perceived improvement. We found no clinical or urodynamic parameter that would be a contraindication to AUS placement for post-RP incontinence.

Does indigo carmine prevent early artificial urinary sphincter cuff erosion?

INTRODUCTION: Urethral erosion following artificial urinary sphincter (AUS) placement is hypothesized to be secondary to unrecognized intra-operative urethral injury. Intra-urethral indigo carmine solution (ICS), a blue dye, following urethral mobilization should identify intra-operative urethrotomy and prevent early post-operative cuff erosion. METHODS: Retrospective review was completed of all men undergoing AUS (AMS 800 device) insertion between January 2000 and January 2005 for post prostatectomy stress incontinence at one institution. Operative reports were examined for use of intra-operative injection of ICS as well as documentation of urethral injury. Post-operative course was reviewed for evidence of early cuff erosion. All patients were followed a minimum of 6 months post-operatively. RESULTS: Seventy-eight men underwent AUS placement during the investigative period. Forty-one men received intra-operative ICS injection following urethral mobilization and 37 men did not. ICS identified one intra-operative urethral injury. No urethral injuries were noted in the non-injection group. The ICS group suffered 3 (7.3%) early urethral erosions; the control group had one early urethral erosion (2.7%). CONCLUSION: Intra-operative ICS use is easy, safe, and able to identify urethral injury. However, its use did not preclude the incidence of early cuff erosion. This may postulate the existence of early urethral cuff erosion as a separate entity not dependent on intra-operative urethrotomy.

Salvage radiotherapy for isolated prostate specific antigen increase after radical prostatectomy: evaluation of prognostic factors and creation of a prognostic scoring system.

PURPOSE: This study was performed to evaluate the results and prognostic factors associated with radiotherapy for a detectable serum prostate specific antigen level after radical prostatectomy. MATERIALS AND METHODS: From July 1987 through July 2003, 368 patients received radiotherapy for a detectable prostate specific antigen level (biochemical relapse) as the sole evidence of recurrence after radical prostatectomy for node negative prostate cancer. Estimated survival and relapse-free probabilities were obtained via Kaplan-Meier estimation. Associations of patient factors with survival and biochemical relapse were investigated using Cox proportional hazards models. RESULTS: With a median followup of 5 years the 5 and 8-year freedom from biochemical relapse were an estimated 46% (95% CI 41%-53%) and 35% (95% CI 29%-43%) while survival was 92% (95% CI 89%-95%) and 80% (95% CI 74%-87%), respectively. Patient and treatment variables showing evidence of association with biochemical relapse on multivariate analysis included pathological stage T3a or less vs T3b (seminal vesicle involvement, p = 0.029), pathological Gleason score 7 or less vs 8 or greater (p <0.001) and pre-radiotherapy prostate specific antigen (p <0.001). Four biochemical failure risk groups were created by assigning seminal vesicle involvement, Gleason score and pre-radiotherapy prostate specific antigen each a score of 0 to 2. These individual scores were summed. The freedom from biochemical failure at 5 years for each risk group was 0 to 1-69%, 2-53%, 3-26% and 4 to 5-6%. CONCLUSIONS: The presence of seminal vesicle involvement and high Gleason score in the radical prostatectomy specimen are inherent predictors of adverse outcome. Early referral for salvage radiotherapy can decrease subsequent biochemical relapse.

Solitary breast mass as initial presentation of clinically silent metastatic renal cell carcinoma.

Metastasis to the breast from extramammary tumors is rare. Breast metastases of renal cell carcinoma (RCC) origin have been described in sporadic case reports. We present a patient with a solitary breast mass representing the manifestation of clinically silent, metastatic RCC. A 76-year-old female was 12 years prior removed from radical nephrectomy for localized RCC. Her new breast mass was identified on physical examination. Pathology of the resected mass was diagnostic of metastatic RCC and subsequent imaging studies demonstrated a 1.9 cm renal mass in her solitary kidney. The patient elected subcutaneous Interleukin-2 immunotherapy as primary treatment for her recurrent RCC.

Systematic transperineal ultrasound-guided template biopsy of the prostate: three-year experience.

OBJECTIVES: To review the technique of transperineal saturation prostate biopsy and to update our results on patients at high risk of prostate cancer. METHODS: A total of 210 men who met the study inclusion criteria underwent systematic transperineal ultrasound-guided template biopsy of the prostate. All patients had previously undergone at least one set of transrectal prostate biopsies and 170 (81%) had undergone two or more. The mean number of prostate cores obtained before the template biopsy was 17.4. A mean of 21.2 cores (range 12 to 41) were obtained at the template biopsy, depending on prostate size. The study inclusion criteria included prostate-specific antigen level of 10 ng/mL or greater, prostate-specific antigen velocity of 0.75 ng/mL per year or greater, or the presence of prostatic intraepithelial neoplasia and/or atypical small cell acinar proliferation on the previous biopsy. RESULTS: Adenocarcinoma was detected in 78 men (37%). Cancer was detected in the transition zone in 60 (77%) of these 78 men, including 36 (46%) in whom cancer was identified uniquely in the transition zone. Gleason sum 6 (range 3 to 9) was the most common biopsy grade. Thirty patients underwent radical prostatectomy, and 27 (90%) had pathologic Stage pT2 disease as the final pathologic stage. Complications from biopsy were limited to postprocedural urinary retention in 11% of patients. CONCLUSIONS: A systematic transperineal template biopsy provides uniform sampling of the entire prostate. This technique appears to enhance the identification of transition zone cancers not detected by previous transrectal prostate biopsy in patients at high risk of prostate adenocarcinoma.

Acute urinary retention after transperineal template-guided prostate biopsy.

PURPOSE: Urinary retention occurs in 5%-36% of patients with prostate cancer after implantation of radioactive seeds for brachytherapy. We used transperineal biopsy as a model to determine the influence of needle trauma on urinary retention. METHODS AND MATERIAL: We retrospectively reviewed medical records of 157 men with high risk of prostate cancer who underwent systematic ultrasound-guided biopsy of the prostate with the transperineal template technique and an 18-gauge automated biopsy device. RESULTS: Eighteen of 157 patients (11.5%; 95% confidence interval, 6.9%-17.5%) had urinary retention within 48 hours after biopsy. Median age was 68.5 years in patients with retention vs. 67.0 years in patients without (p = 0.319); median calculated prostate volume, 76.5 vs. 51.5 mL (p = 0.015); and median number of biopsy cores, 22.0 vs. 20.0 (p = 0.038). Age distribution differed between groups (p = 0.047), with more younger men in the no-retention group. On multivariate analysis, only number of biopsy cores significantly predicted urinary retention (p = 0.003). Four patients required transurethral resection; 1 had an indwelling catheter until radical prostatectomy; and 13 were catheter-free within 1-5 days. CONCLUSIONS: Needle trauma alone may cause urinary retention in men undergoing transperineal procedures. The number of needle incursions and prostate size are predictors of postprocedure urinary retention.

Conservative management of incidental contrast-enhancing renal masses as safe alternative to invasive therapy.

OBJECTIVES: To describe small contrast-enhancing renal masses suggestive of cancer that were managed conservatively with watchful waiting and serial computed tomography scans. Advanced diagnostic imaging has led to the increased incidental detection of renal masses in patients whose multiple comorbid conditions preclude invasive management. METHODS: A retrospective review was conducted of 29 consecutive patients with 29 incidentally detected asymptomatic renal masses less than 3.5 cm in diameter that were managed conservatively with watchful waiting (because of patient wishes or multiple comorbid conditions) and serial computed tomography scans. RESULTS: The average patient age was 70 years (range 51 to 88), and the average duration of follow-up imaging was 32 months (range 10 to 89). The average number of follow-up computed tomography scans was 4.9 per patient (range 1 to 11). The average width of the renal masses at diagnosis was 1.83 cm (range 0.4 to 3.5), and the average change in size per year was 0.12 cm for all patients. Four patients underwent radical nephrectomy because of growth of the renal mass (n = 1) or patient wishes (n = 3). The histologic findings in 3 of these 4 patients were consistent with renal cell carcinoma. Two patients underwent radiofrequency ablation of the masses. At last follow-up, metastatic disease had not developed in any patient, and no patient had died of renal cell carcinoma. Two patients had died of other causes. CONCLUSIONS: The results of our study showed that when comorbid conditions or patient wishes preclude invasive treatment, contrast-enhancing renal masses less than 3.5 cm wide that are suggestive of cancer can be safely managed with watchful waiting and serial computed tomography scans.

Prediction of genitourinary tract morbidity after brachytherapy for prostate adenocarcinoma.

OBJECTIVE: To investigate whether preoperative genitourinary variables in patients undergoing brachytherapy for localized prostate adenocarcinoma could predict postoperative genitourinary tract morbidity. PATIENTS AND METHODS: We retrospectively reviewed medical records of 105 men who received either iodine 125 or palladium 103 radioactive seed implants with or without external beam radiotherapy or hormone blockade from January 1, 1998, through December 31, 2000, at the Mayo Clinic in Jacksonville, Fla. Patients with one or more of the following were classified as having a high risk of postoperative genitourinary tract morbidity: American Urological Association symptom scores greater than 15, maximum urinary flow rate less than 10 mL/s, postvoid residual urinary volume greater than 100 mL, or prostate volume greater than 40 cm3. Of the 105 men, 59 (56%) were classified as high risk and 46 (44%) as low risk. Mean follow-up after brachytherapy was 23.6 months. Modified Radiation Therapy Oncology Group scores were used to assess postoperative genitourinary tract morbidity. The term significant genitourinary tract morbidity was applied to patients with a Radiation Therapy Oncology Group grade of 3 or 4 after at least 6 months of follow-up. RESULTS: Significant morbidity occurred in 37% of high-risk vs 15% of low-risk patients (P = .006). In high-risk patients, transurethral resection or incision of the prostate was required in 5 patients, urethral dilation in 4, direct-vision internal urethrotomy in 1, and placement of a suprapubic catheter in 1. In low-risk patients, transurethral incision of the prostate was required in only 1 patient. Urinary flow rate was a significant individual predictor of postoperative morbidity (P = .03). CONCLUSIONS: A combination of urinary flow rate, prostate volume, postvoid residual urinary volume, and American Urological Association symptom score can help identify patients with underlying voiding dysfunction. Urinary flow rate was a statistically significant predictor of genitourinary tract morbidity after brachytherapy for localized prostate adenocarcinoma. Patients and physicians should consider these factors before a patient decides to undergo brachytherapy.

Benign prostatic hypertrophy which nonoperative strategies are best?

Benign prostatic hypertrophy is one of the common complaints of older men who visit their primary care physicians. Nonoperative therapy, such as drug therapy or lifestyle modification, is aimed primarily at reducing bothersome lower urinary tract symptoms and preventing serious morbidity such as urinary retention and renal function impairment. As more men reach advanced age, it becomes crucial for the primary care physician to be aware of the epidemiology, pathophysiology, natural history, clinical presentation, and therapeutic modalities available for the treatment of clinically significant cases.
