Dynamic approach to transurethral resection of large prostate adenoma

Since it is not how much tissue is removed but rather how much is left behind that attests to the quality of a TURP, an explanation of four common complications is offered hoping that with this increased understanding the resectionist will be more comfortable with the procedure and undertake careful resection of larger prostate glands. The following guidelines are offered: (1) allow time after the initial resection of easily reached adenoma for the delivery by the contracting capsule of the peripheral adenoma and the apical masses. One can always return to these areas for further rapid resection. (2) Do not resect within 0.5 or 1.0 cm of the bladder neck until the very end of the procedure. This will minimize the undermining of the vesicle neck and the "climbing" of the trigone. It will also allow for the preservation of vesicle mucosa up to or over the bladder neck thus lessening the chance of later contracture at this site. (3) Do not resect the juxta capsular adenoma in the "levator ani area" until near the end of the procedure.     

Hyponatraemia after transurethral resection of the prostate

Transurethral resection (TUR) syndrome is a complication of transurethral resection of the prostate characterized by bradycardia, hypotension and postoperative confusional state, which is generally attributed to hyponatraemia occurring during or immediately after operation. In a prospective study of 100 consecutive patients undergoing transurethral resection of the prostate, changes in serum sodium were estimated before and after operation and correlated with various parameters including weight of prostate resected, volume of irrigant fluid and resection time. Seven patients showed a significant drop (greater than 10 mmol/litre) in serum sodium: two of these had the clinical features of TUR syndrome and one of them died. The pathogenesis and management of this syndrome are discussed.     

经尿道单极前列腺剜除术与经尿道等离子前列腺剜除术的疗效及安全性比较

目的探讨经尿道单极前列腺剜除术与经尿道等离子前列腺剜除术的疗效及安全性比较。方法在2006年11月1日至2010年8月1日确诊为前列腺增生（BPH）的男性患者75例,符合纳入标准的患者随机分成两组,因前列腺包膜与腺体粘连紧密无法行剜除术3例,退出试验。经尿道单极前列腺剜除术组（TUERP）34例与经尿道等离子前列腺剜除术组（PKERP）38例,比较两组的手术时间、术中出血量、术后留置导尿管时间和术后住院时间,两组术后3个月与术前国际前列腺症状0PSS）、生活质量（QOL）评分及最大尿流率（Qmax）检查、残留尿量（RUV）、前列腺重量进行比较。结果两组间各项观察指标经独立样本t检验,差异无统计学意义（P〉0．05）;各项观察指标手术前后比较,经配对t检验,差异有统计学意义（P〈0．05）。结论在保证手术技巧娴熟前提下,TUREP术与PKERP术相比,同样能够缩短手术时间、减少术中出血量、缩短术后留置导尿管时间和术后住院时间,其有效性和安全性相近,值得推广实行。     

Subacute hyponatraemia after transurethral resection of the prostate

We present a case of subacute hyponatraemia which developed 3 days after a transurethral resection of the prostate. Symptoms consisted of nausea, vomiting and headache. Release of vasopressin due to excessive surgical bleeding, combined with liberal oral and intravenous administration of sodium-free fluids, was considered to be the cause.     

Pubic symphysitis after transurethral resection of the prostate

Purpose

Pubic symphysitis (PS) after urological operations is uncommon. This is a systematic single-institution review of patients with transurethral resection of the prostate (TUR-P) with the aim to determine the incidence of PS after TUR-P and to identify a risk profile.

Materials and methods

In the past 15 years, 12,118 transurethral operations were performed in our department, 33.4 % (n = 4045) were TUR-P, and 84.6 % (n = 3421) had routine suprapubic trocar placement. A systematic retrospective analysis identified 12 patients, who developed PS (0.297 %).

Results

Median age was 69.5 years (64–83). All patients had voiding difficulties. Urine culture had been positive in three cases. All 12 TUR-Ps were monopolar resections, and n = 11 patients had a suprapubic trocar. Median resection weight was 47.5 g (10–100). Two patients had a perforation of the capsule. Histopathological examination revealed chronic prostatitis in nine cases. After 1.0 ± 1.2 months, all patients developed pain in the pubic region. All patients underwent MRI, which suggested PS. Symptomatic and antibiotic medications were administered. Final outcome was resolution of symptoms in all patients after 3.8 ± 5.6 months. No patient retained voiding difficulties.

Conclusion

PS remains a rare complication after TUR-P. We could not identify a single cause for developing PS. In our study, suprapubic trocar placement (11/12), chronic prostatic inflammation (9/12), previous UTI (3/12) and extended resection (2/12) were overrepresented. Inflammatory, thermic and/or surgical damage of the capsule may be causative. Patients require antibiotic and symptomatic medication. However, prognosis for remission is excellent.

     

'Cardiac' enzymes after transurethral resection of the prostate

Postoperative serial determinations of serum total creatine kinase (CK) and the CK-B subunit (by immunoinhibition), and of total lactate dehydrogenase (LD) and isoenzyme LD-1 (by immunoprecipitation), were performed in 16 and 9 patients, respectively, after uncomplicated transurethral resection of the prostate (TURP). Total CK remained unchanged. An early, modest increase in serum CK-B activity, accompanied by an unusually high CK-B/total CK relation, correlated significantly with duration of operation and amount of tissue resected. A slight, early elevation of the total LD level was not accompanied by an increase in LD-1. If the possibility of small increases in CK-B and LD from the prostate is taken into consideration, routine criteria for diagnosing myocardial damage may be applied after TURP.     

Prophylactic antibiotics after transurethral resection of prostate

We studied whether or not prophylactic use of antibiotics following transurethral resection of prostate (TUR-P) was needed. The subjects were 152 patients preoperatively passing sterile urine who underwent TUR-P. They were divided into three groups: 35 with no use of antibiotics (no prophylaxis group), 70 with one day use of antibiotics (one day-prophylaxis group) and 47 with use of antibiotics until pyuria disappeared (long term-group). The three groups did not differ in their rates of fever episodes (greater than or equal to 38.0 degrees C) during the first two weeks nor in the time of disappearance of pyuria. The no prophylaxis group and the one day-group differed statistically in their cumulative rates of bacteriuria (greater than 10(4) CFU/ml) on the postoperative third day: 4 patients (11.4%) in the no prophylaxis group and none in the one day group (p less than 0.01). On the 90th day, however, no significant difference was found in that rate: 22 patients (62.9%) in the no prophylaxis group and 32 patients (45.7%) in the one day group, 70% of the bacteria isolated from urine during the follow up were Gram positive cocci. The time to the elimination of pyuria was not influenced by the use of antibiotics. Our study suggests that postoperative antibiotics for patients passing sterile urine is not necessary following TUR-P.     

前列腺腔内术后尿道狭窄原因及处理

目的探讨前列腺患者腔内手术后尿道狭窄的原因及处理方法。方法经尿道前列腺汽化电切术后尿道狭窄32例，术前均行膀胱镜检未见尿道狭窄，术后出现排尿困难，经尿道探杆检查、膀胱镜检及尿道造影明确诊断为尿道狭窄。其中14例为尿道外口狭窄，9例为尿道球膜部狭窄，4例为阴茎部尿道狭窄缘于尿道扩张造成，5例为前列腺尿道部疤痕狭窄。18例行尿道扩张治愈，7例行尿道内切开加尿道扩张治愈，4例前列腺部尿道狭窄再次电切治愈，3例行尿道成形术。结果32例治疗后能维持通畅的排尿，其中4例患者须定期尿扩随访。结论经尿道前列腺汽化电切术后尿道狭窄主要发生于尿道外口及前尿道，与器械、留置尿管、感染及尿道扩张等因素相关。治疗方法主要为尿道扩张及尿道内切开，尤应重视术后的尿扩随访。     

Holmium laser enucleation of the prostate versus transurethral resection of the prostate: a randomized clinical trial

Objective

To evaluate the efficacy and safety of holmium laser enucleation of the prostate (HoLEP) and transurethral resection of the prostate (TURP), for treatment of benign prostatic hyperplasia (BPH).

Methods

A total of 164 cases of BPH were selected from patients who were hospitalized between January 2010 and December 2011. Patients had received either HoLEP or TURP treatment. Clinical data were collected from the perioperative period, 1 month after surgery, and 12 months after surgery.

Results

There was no significant difference between the two groups in the maximum urinary flow rate (Q _max), postvoid residual volume (PVR), international prostate symptom score (IPSS), or quality-of-life score (QOL score) at 1 month after surgery (p = 0.56, p = 0.346, p = 0.536 and p = 0.145, respectively). However, after 12 months, patients from the HoLEP group demonstrated better scores in Q _max, PVR, IPSS, and QOL than those from the TURP group (p = 0.037, p = 0.003, p < 0.001 and p = 0.019, respectively). The two groups had comparable operation time (p = 0.105), catheterization time (p = 0.173), and length of hospital stay (p = 0.395), but were statistically different in the weight of resected prostate tissue (p < 0.001), bladder irrigation time (p < 0.001), hemoglobin levels (p = 0.011), and blood sodium levels (p = 0.002) after surgery.

Conclusions

Compared to TURP, HoLEP was safer and had better long-term efficacy as assessed by multiple quantitative measures. Therefore, HoLEP may present a better option in the treatment of BPH.     

Introducing holmium laser enucleation of the prostate alongside transurethral resection of the prostate improves outcomes of each procedure

Introduction

Holmium laser enucleation of the prostate (HoLEP) is recognised as an alternative to transurethral resection of the prostate (TURP). HoLEP has been demonstrated to be at least as effective as TURP with less morbidity but its introduction to practice has been limited in part by the learning curve of a novel procedure. This study examined the effects of introducing HoLEP alongside an established practice of TURP on early morbidity and length of hospital stay (LOS).

Methods

A retrospective review of all patients who underwent HoLEP and TURP between April 2007 and July 2011 was undertaken. HoLEP was introduced in April 2008; patients undergoing TURP before this were considered as a historical control group. Data were collected concerning resection/enucleation weight, blood transfusions and LOS.

Results

Overall, 772 patients underwent HoLEP or TURP within the 52-month study period: 164 underwent TURP prior to the introduction of HoLEP (TURP-A), 425 had TURP after the introduction of HoLEP (TURP-B) and 183 underwent HoLEP. The mean removed weight was 24g (standard deviation [SD]: 21g) for TURP-A, 19g for TURP-B (SD: 16g) and 38g (SD: 32g) for HoLEP (p<0.005). Blood transfusion rates were 5.5%, 2.2% and 1.6% for the TURP-A, TURP-B and HoLEP groups respectively (p<0.05). For TURP-A patients, the mean LOS was 5.6 days (SD: 3.5 days, 95% confidence interval [CI]: 5.3–6.0 days). The mean LOS for TURP-B patients was 4.4 days (SD: 4.4 days, 95% CI: 4.2–4.8 days). HoLEP patients had a mean LOS of 3.0 days (SD: 3.0 days, 95% CI: 2.6–3.4 days).

Conclusions

The introduction of HoLEP alongside TURP is associated with lower rates of blood transfusion and shorter LOS for all patients. This is likely to be due to the use of HoLEP rather than TURP in patients with larger prostates, who are more likely to have complications.     

A Fournier's gangrene after transurethral resection of the prostate

Fournier's gangrene is a rapidly progressive and potentially lethal disease that affects the perineum and mal genitalia. Predisposing factors included age, diabetes, alcoholism, malnutrition, and low socio-economic status. Herein, we present a 70-year-old patient who developed Fournier's gangrene following transurethral resection of the prostate. He had no predispositional factors to develop Fournier's gangrene.     

Persistent detrusor overactivity after transurethral resection of the prostate

Detrusor overactivity is associated with aging and benign prostatic obstruction and often causes the troublesome symptoms of urgency and urgency incontinence (overactive bladder), persistent detrusor overactivity after transurethral resection of the prostate being the cause of more than a third of poor symptomatic outcomes following surgery. Most of the evidence currently suggests that neurons of the urothelium at the bladder neck play a significant role in the genesis of detrusor overactivity. Treatment options including botulinum toxin injections and intravesical vanilloids have been studied in the treatment of persistent detrusor overactivity, but further studies are needed specifically in patients with persistent detrusor overactivity after transurethral resection of the prostate. As urodynamic studies are able to predict a proportion of postoperative failures, more widespread use is advocated by many in the routine assessment of lower urinary tract symptoms thought to be due to benign prostatic obstruction.
