Trends, characteristics, and outcomes of placenta accreta spectrum: a national study in the United States

BACKGROUND

Although an infrequent occurrence, the placenta can adhere abnormally to the gravid uterus leading to significantly high maternal morbidity and mortality during cesarean delivery. Contemporary national statistics related to a morbidly adherent placenta, referred to as placenta accreta spectrum, are needed.

OBJECTIVE

This study aimed to examine national trends, characteristics, and perioperative outcomes of women who underwent cesarean delivery for placenta accreta spectrum in the United States.

STUDY DESIGN

This is a population-based retrospective, observational study querying the National Inpatient Sample. The study cohort included women who underwent cesarean delivery from October 2015 to December 2017 and had a diagnosis of placenta accreta spectrum. The main outcome measures were patient characteristics and surgical outcomes related to placenta accreta spectrum assessed by the generalized estimating equation on multivariable analysis. The temporal trend of placenta accreta spectrum was also assessed by linear segmented regression with log transformation.

RESULTS

Of 2,727,477 cases who underwent cesarean delivery during the study period, 8030 (0.29%) had the diagnosis of placenta accreta spectrum. Placenta accreta was the most common diagnosis (n=6205, 0.23%), followed by percreta (n=1060, 0.04%) and increta (n=765, 0.03%). The number of placenta accreta spectrum cases increased by 2.1% every quarter year from 0.27% to 0.32% (P=.004). On multivariable analysis, (1) patient demographics (older age, tobacco use, recent diagnosis, higher comorbidity, and use of assisted reproductive technology), (2) pregnancy characteristics (placenta previa, previous cesarean delivery, breech presentation, and grand multiparity), and (3) hospital factors (urban teaching center and large bed capacity hospital) represented the independent characteristics related to placenta accreta spectrum (all, P<.05). The median gestational age at cesarean delivery was 36 weeks for placenta accreta and 34 weeks for both placenta increta and percreta vs 39 weeks for non-placenta accreta spectrum cases (P<.001). On multivariable analysis, cesarean delivery complicated by placenta accreta spectrum was associated with increased risk of any surgical morbidities (78.3% vs 10.6%), Centers for Disease Control and Prevention-defined severe maternal morbidity (60.3% vs 3.1%), hemorrhage (54.1% vs 3.9%), coagulopathy (5.3% vs 0.3%), shock (5.0% vs 0.1%), urinary tract injury (8.3% vs 0.2%), and death (0.25% vs 0.01%) compared with cesarean delivery without placenta accreta spectrum. When further analyzed by subtype, cesarean delivery for placenta increta and percreta was associated with higher likelihood of hysterectomy (0.4% for non-placenta accreta spectrum, 45.8% for accreta, 82.4% for increta, 78.3% for percreta; P<.001) and urinary tract injury (0.2% for non-placenta accreta spectrum, 5.2% for accreta, 11.8% for increta, 24.5% for percreta; P<.001). Moreover, women in the placenta increta and percreta groups had markedly increased risks of surgical mortality compared with those without placenta accreta spectrum (increta, odds ratio, 19.9; and percreta, odds ratio, 32.1).

CONCLUSION

Patient characteristics and outcomes differ across the placenta accreta spectrum subtypes, and women with placenta increta and percreta have considerably high surgical morbidity and mortality risks. Notably, 1 in 313 women undergoing cesarean delivery had a diagnosis of placenta accreta spectrum by the end of 2017, and the incidence seems to be higher than reported in previous studies.

Damage Control for renal trauma: the more conservative the surgeon, better for the kidney

Urologic trauma is frequently reported in patients with penetrating trauma. Currently, the computerized tomography and vascular approach through angiography/embolization are the standard approaches for renal trauma. However, the management of renal or urinary tract trauma in a patient with hemodynamic instability and criteria for emergency laparotomy, is a topic of discussion. This article presents the consensus of the Trauma and Emergency Surgery Group (CTE) from Cali, for the management of penetrating renal and urinary tract trauma through damage control surgery. Intrasurgical perirenal hematoma characteristics, such as if it is expanding or actively bleeding, can be reference for deciding whether a conservative approach with subsequent radiological studies is possible. However, if there is evidence of severe kidney trauma, surgical exploration is mandatory and entails a high probability of requiring a nephrectomy. Urinary tract damage control should be conservative and deferred, because this type of trauma does not represent a risk in acute trauma management.

Self-Induced Trauma to the Genitalia: a Review of the Literature and Management Schemes

PURPOSE OF REVIEW

Self-induced genital trauma is rare, and prompt and evidence-based early intervention can improve the urinary and sexual function of these complex patients. This review has surveyed current literature and treatment trends to evaluate the clinical approach to managing genital trauma.

RECENT FINDINGS

A literature review was performed regarding self-induced genitalia trauma and trauma management between 2000 and 2019 using MEDLINE® database, the Cochrane Library® Central Search, Web of Science, and Google Scholar. In total, 42 articles were considered relevant and included in this review. Self-induced trauma can be appropriately managed with a multidisciplinary approach. Treatment goals are to preserve urinary, sexual, and reproductive function. Specific evaluation includes mechanism of injury, imaging, and determining the extent of injury and surgical repair, if indicated. Due to the rarity of these injuries and their emergent nature, much of the management is based on retrospective data. Further research is needed to improve long-term functional outcomes in trauma patients.

Outcomes following a clinical algorithm allowing for delayed hysterectomy in the management of severe placenta accreta spectrum

BACKGROUND

The incidence of placenta accreta spectrum is rising. Management is most commonly with cesarean hysterectomy. These deliveries often are complicated by massive hemorrhage, urinary tract injury, and admission to the intensive care unit. Up to 60% of patients require transfusion of ≥4 units of packed red blood cells. There is also a significant risk of death of up to 7%.

OBJECTIVE

The purpose of this study was to assess the outcomes of patients with antenatal diagnosis of placenta percreta that was managed with delayed hysterectomy as compared with those patients who underwent immediate cesarean hysterectomy.

STUDY DESIGN

We performed a retrospective study of all patients with an antepartum diagnosis of placenta percreta at our large academic institution from January 1, 2012, to May 30, 2018. Patients were treated according to standard clinical practice that included scheduled cesarean delivery at 34-35 weeks gestation and intraoperative multidisciplinary decision-making regarding immediate vs delayed hysterectomy. In cases of delayed hysterectomy, the hysterotomy for cesarean birth used a fetal surgery technique to minimize blood loss, with a plan for hysterectomy 4-6 weeks after delivery. We collected data regarding demographics, maternal comorbidities, time to interval hysterectomy, blood loss, need for transfusion, occurrence of urinary tract injury and other maternal complications, and maternal and fetal mortality rates. Descriptive statistics were performed, and Wilcoxon rank-sum and chi-square tests were used as appropriate.

RESULTS

We identified 49 patients with an antepartum diagnosis of placenta percreta who were treated at Vanderbilt University Medical Center during the specified period. Of these patients, 34 were confirmed to have severe placenta accreta spectrum, defined as increta or percreta at the time of delivery. Delayed hysterectomy was performed in 14 patients: 9 as scheduled and 5 before the scheduled date. Immediate cesarean hysterectomy was completed in 20 patients: 16 because of intraoperative assessment of resectability and 4 because of preoperative or intraoperative bleeding. The median (interquartile range) estimated blood loss at delayed hysterectomy of 750 mL (650-1450 mL) and the sum total for delivery and delayed hysterectomy of 1300 mL (70 -2150 mL) were significantly lower than the estimated blood loss at immediate hysterectomy of 3000 mL (2375-4250 mL; P<.01 and P=.037, respectively). The median (interquartile range) units of packed red blood cells that were transfused at delayed hysterectomy was 0 (0-2 units), which was significantly lower than units transfused at immediate cesarean hysterectomy (4 units [2-8.25 units]; P<.01). Nine of 20 patients (45%) required transfusion of ≥4 units of red blood cells at immediate cesarean hysterectomy, whereas only 2 of 14 patients (14.2%) required transfusion of ≥4 units of red blood cells at the time of delayed hysterectomy (P=.016). There was 1 maternal death in each group, which were incidences of 7% and 5% in the delayed and immediate hysterectomy patients, respectively.

CONCLUSION

Delayed hysterectomy may represent a strategy for minimizing the degree of hemorrhage and need for massive blood transfusion in patients with an antenatal diagnosis of placenta percreta by allowing time for uterine blood flow to decrease and for the placenta to regress from surrounding structures.

Kidney and uro-trauma: WSES-AAST guidelines

Renal and urogenital injuries occur in approximately 10-20% of abdominal trauma in adults and children. Optimal management should take into consideration the anatomic injury, the hemodynamic status, and the associated injuries. The management of urogenital trauma aims to restore homeostasis and normal physiology especially in pediatric patients where non-operative management is considered the gold standard. As with all traumatic conditions, the management of urogenital trauma should be multidisciplinary including urologists, interventional radiologists, and trauma surgeons, as well as emergency and ICU physicians. The aim of this paper is to present the World Society of Emergency Surgery (WSES) and the American Association for the Surgery of Trauma (AAST) kidney and urogenital trauma management guidelines.

Unintended hysterotomy extension during caesarean delivery: risk factors and maternal morbidity

We conducted an observational retrospective cohort study to evaluate the risk factors and the maternal morbidity associated with unintended extensions of the hysterotomy during caesarean delivery. We evaluated 2707 women who underwent low-transverse caesarean deliveries in 2011 at an academic, tertiary-care hospital. Hysterotomy extensions were identified through operative reports. Of the 2707 caesarean deliveries, 392 (14.5%) had an unintended hysterotomy extension. On the multivariable regression modelling, neonatal weight (OR 1.42; 95%CI 1.17-1.73), the arrest of labour [first-stage arrest (2.42; 1.73-3.38); second-stage arrest (5.54; 3.88-7.90)] and a non-reassuring foetal status (1.65; 1.20-2.25) were significantly associated with hysterotomy extensions. Hysterotomy extensions were significantly associated with an increased morbidity including an estimated blood loss >1200 millilitres (2.06; 1.41-3.02), a decline in postoperative haemoglobin ≥3.7 g/dL (2.07; 1.35-3.17), an evaluation for lower urinary tract injury (5.58; 3.17-9.81), and a longer operative time (8.11; 6.33-9.88). Based on these results, we conclude that unintended hysterotomy extensions significantly increase the maternal morbidity of caesarean deliveries. Impact statement What is already known on this subject? Maternal morbidity associated with caesarean delivery (CD) is significantly greater than that in vaginal delivery. Unintended extensions of the hysterotomy occur in approximately 4-8% of CDs and are more common after a prolonged second stage of labour. The morbidity associated with hysterotomy extensions has been incompletely evaluated. What do the results of this study add? We demonstrate a rate of hysterotomy extension in a general obstetric population of approximately 15%, which is higher than previously reported estimates, and represents a potential doubling of the rate of the unintended hysterotomy extensions in recent years. The most significant risk factor for a hysterotomy extension was a second-stage labour arrest with a fourfold increase in the frequency of extensions. A hysterotomy extension is a significant independent risk factor for an intraoperative haemorrhage, a drop in postoperative haemoglobin, an intraoperative evaluation for lower urinary tract injury, and longer CD operative times. What are the implications of these findings for clinical practice and/or further research? A second-stage arrest is a strong independent risk factor for a hysterotomy extension. Recent re-evaluations of the labour curve that extend the second stage of labour will likely increase the frequency of CDs performed after a prolonged second stage. In these scenarios, obstetricians should be prepared for an unintended hysterotomy extension and for the possibility of a longer procedure with the increased risks of blood loss and the need for evaluation of the lower urinary tract.

Outcomes in dogs with uroabdomen: 43 cases (2006-2015)

OBJECTIVE To determine the rate of and factors associated with survival to hospital discharge in dogs with uroabdomen. DESIGN Retrospective case series. ANIMALS 43 dogs with uroabdomen confirmed at 2 veterinary teaching hospitals from 2006 through 2015. PROCEDURES Medical records were reviewed and data extracted regarding cause and location of urinary tract rupture, serum creatinine concentration and other variables at hospital admission, and outcomes. Variables were tested for associations with survival to hospital discharge. RESULTS Urinary tract rupture occurred in the urinary bladder (n = 24 [56%]), urethra (11 [26%]), kidney (2 [5%]), ureter (1 [2%]), both the urinary bladder and kidney (1 [2%]), and undetermined sites (4 [9%]). Rupture causes included traumatic (20 [47%]), obstructive (9 [21%]), and iatrogenic (7 [16%]) or were unknown (7 [16%]). Surgery was performed for 37 (86%) dogs; the defect was identified and surgically corrected in 34 (92%) of these dogs. Hypotension was the most common intraoperative complication. Nineteen dogs had information recorded on postoperative complications, of which 10 (53%) had complications that most often included death (n = 3) and regurgitation (3). Thirty-four (79%) dogs survived to hospital discharge. Dogs with intraoperative or postoperative complications were significantly less likely to survive than dogs without complications. Serum creatinine concentration at admission was not associated with survival to discharge. CONCLUSIONS AND CLINICAL RELEVANCE A high proportion of dogs with uroabdomen survived to hospital discharge. No preoperative risk factors for nonsurvival were identified. Treatment should be recommended to owners of dogs with uroabdomen.

[Cytological evaluation of urothelial damage in extracorporeal shock-wave lithotripsy]

INTRODUCTION

The study proposed a technique for early detection of the damaging effect of shock waves on the urinary tract tissues, for monitoring the state of urothelial cells in the early post-procedure period and choosing an adequate method for preventing and managing possible complications.

MATERIALS AND METHODS

The study analyzed the urine samples of 300 patients aged 20 to 50 years, who for the first time underwent ESWL for kidney stones. The urine sediment smears were fixed in the May-Grunwald stain and stained with azure eosin solution according to Pappenheim. Besides evaluating general cytologic characteristics, a morphometric examination of urine sediment was performed.

RESULTS AND DISCUSSION

To define quantitative parameters, the total number of epithelial cells (ep) was determined with further calculation of the mean number of epithelial cells in the field of view (ep= ep/10). Correlation between the number of abnormal epithelial cells (cp) and the total number of epithelial cells (ep) was analyzed. The resulted "destruction index" (DI) was the "pool" of all cytopathological changes in epithelial cells DI = cp/ep. Immediately after ESWL, DI markedly increased with significant difference (<0.05) in numeric values. Two hours after the procedure, the DI reduced compared to the previous value. And only at day 4 DI was close to the norm, although remaining somewhat elevated.

CONCLUSION

Extracorporeal shock waves lithotripsy produces the acute urothelial damage resulting in cytopathological changes of varying severity. The above-mentioned technique provides objective and highly significant clinical and diagnostic information on the state of the urothelium after the exposure to shock waves.

Acute urinary morbidity after a permanent 125I implantation for localized prostate cancer

We evaluated the predictive factors of acute urinary morbidity (AUM) after prostate brachytherapy. From November 2005 to January 2007, 62 patients with localized prostate cancer were treated using brachytherapy. The (125)Iodine ((125)I) seed-delivering method was a modified peripheral pattern. The prescribed dose was 144 Gy. Urinary morbidity was scored at 3 months after implantation. The clinical and treatment parameters were analysed for correlation with AUM. In particular, in this study, Du90 (the minimal dose received by 90% of the urethra), Dup90 (the minimal dose received by 90% of the proximal half of the urethra on the bladder side) and Dud90 (the minimal dose received by 90% of the distal half of the urethra on the penile side) were analysed. We found that 43 patients (69.4%) experienced acute urinary symptoms at 3 months after implantation. Of them, 40 patients had Grade 1 AUM, one patient had Grade 2 pain, and two patients had Grade 2 urinary frequency. None of the patients had ≥Grade 3. Univariate and multivariate analysis revealed that Du90 and Dup90 were significantly correlated with AUM. In this study, Du90 and Dup90 were the most significant predictors of AUM after prostate brachytherapy.

[Transvesical laparoendoscopic single-site approach for repair of urinary tract injuries after vaginal or pelvic surgery]

OBJECTIVES

To present a one-center clinical experience of using the transvesical laparoendoscopic single-site surgery (T-LESS) to repair selected urinary tract injuries after vaginal or pelvic surgery.

MATERIAL AND METHODS

From November 2009 to August 2013, 22 women underwent the treatment with the use of the T-LESS technique to repair various complications after gynecologic or uro-gynecologic surgery. Thirteen patients were operated on for iatrogenic foreign bodies, 8 patients underwent a vesicovaginal fistula repair and 1 woman a ureteral reimplantation due to ureterovaginal fistula. In all cases, the TriPort system was established intravesically and standard laparoscopic instruments were used. When needed, bladder and vaginal wall defects were closed with barbed V-Loc suture.

RESULTS

The treatment was successful in all patients. In one case the procedure was converted to open approach. No blood loss or complications were observed. Mean operative time was 78 min. and mean hospitalization time was 3.6 days. The postoperative pain was 0.7 (Visual Analogue Scale) on postoperative day 1. During the average follow-up of 78 months no adverse events related to the method except for one small asymptomatic mesh erosion were noticed.

CONCLUSIONS

The T- LESS approach for repair of selected urinary tract injuries after vaginal or pelvic surgery is a feasible, efficient and safe procedure. It offers excellent visualization inside the bladder, availability of intracorporeal watertight suturing and minimal postoperative pain. Nevertheless, substantial development of the instruments and further investigations are necessary to assess the usefulness of this technique.

Urinary tract injury associated with pelvic fractures

INTRODUCTION

Pelvic trauma associated with urinary tract injury is a severe trauma, mostly caused by traffic accidents and falls from heights. These injuries require urgent treatment and close teamwork between urologic and orthopaedic surgeons.

MATERIAL AND METHODS

In this retrospective study there were analyzed patients with pelvic trauma and extraperitoneal injury of urinary tract, treated surgically at Clinic for Ortopaedic Surgery and Traumatology and Urology Clinic in Clinical Center Nis. Surgical intervention in these patients had been realized as the synchronized work of both orthopaedic and urologic surgeons. The pelvis was treated by external and internal fixation. Mitkovic type external fixator was used for pelvic external fixation. Plating was used for pelvic internal fixation. Pelvic fractures were classified using Tile's classification system. The final functional results had been scored using Majeed score system.

RESULTS

There were 42 patients with the injury of pelvic ring, treated at Clinic for Ortopaedic Surgery and Traumatology and at Urology Clinic, Clinical Center Nis, in the period of 01.01.2011. to 31.12.2013, 30 males and 12 females, with average age of 53.69 (19-84) years old. In 80% of cases pelvic fractures were caused by high energy trauma in traffic accidents. According to Tile's classification, 9 patients (21,42%) had pelvic fracture type A, 23 patients (54,46%) had pelvic fracture type B and 10 patients (23,80%) had pelvic fracture type C. Urinary tract injury was diagnosed in 9 patients (21,42%): 5 patients (11,9%) with bladder injury, 3 patients (7,14%) with posterior urethra injury and 1 patient (2,38%) with both bladder and posterior urethra injury.

CONCLUSION

Urgent repair of extraperitoneal urinary tract injury by urologic surgeons and synchronized pelvic reduction and fixation using external or internal fixation by ortopaedic surgeon, in the same surgical procedure, is the standard method for treatment of this severe injury.

Effect of obesity on perioperative outcomes of laparoscopic hysterectomy

OBJECTIVE

To compare the effect of obesity on perioperative outcomes in women undergoing laparoscopic hysterectomy.

STUDY DESIGN

In this retrospective cohort study, perioperative outcomes of all women who underwent laparoscopic supracervical hysterectomy (LSH) or total laparoscopic hysterectomy (TLH) for benign conditions were compared between obese (body mass index > or = 30 kg/m2) and nonobese women.

RESULTS

Baseline characteristics were similar between 320 (33.0%) obese and 550 (67%) nonobese women except for race and the rates of hypertension and diabetes. The adjusted rates of urinary tract injury, vaginal cuff dehiscence, postoperative fever, and ileus were similar between the groups. For obese women, however, bleeding requiring transfusion was almost 3-fold (3.1 vs. 1.1%, adjusted odds ratio [AOR] 2.93, 95% confidence interval [CI] 1.10-7.80) and laparotomy risk was approximately 2-fold (7.5 vs. 3.5%, AOR 2.35, 95% CI 1.30-4.24) increased. The rate of urinary tract injury was 3.2% when obese women had TLH, but it was 0.3% for LSH performed on nonobese women. Of all 7 cuff dehiscences, 5 (71%) occurred in nonobese women undergoing TLH.

CONCLUSION

Obesity increased the risk of bleeding requiring transfusion and conversion to laparotomy but did not influence the other perioperative complications. On subgroup analysis, LSH in nonobese women seems to result in best outcomes.

[Laboratory diagnosis of urinary tract injuries]

In 238 patients with various surgical diseases of the abdominal cavity, concentration of creatinine in serum and peritoneal cavity exudate was evaluated. In the most cases, no significant differences in creatinine levels were found in these biological fluids, that allowed to recommend to use creatinine level in the exudate, flowing along drainages, as a parameter for dynamic control of nitrogen-excretion renal function. Significant difference in the serum creatinine level and exudate creatinine level was found in cases of injury of organs of urinary system and the penetration of urine into the peritoneal cavity. In these cases (n = 16), creatinine level in the abdominal exudates exceeded the serum level (p < 0.01), that allowed to provide a new method for diagnosis of lesions of the urinary tract.

A scoping review of important urinary catheter induced complications

This study presents a scoping review of the literature on the morbidity and mortality associated with several common complications of urinary catheterization. Data gathered from the open literature were analyzed graphically to gain insights into the most important urinary catheter induced complications. The results reveal that the most significant catheter complications are severe mechanical trauma (perforation, partial urethral damage and urinary leakage), symptomatic bacterial infection, and anaphylaxis, catheter toxicity and hypersensitivity. The data analysis also revealed that the complications with the highest morbidity are all closely related to the mechanical interaction of the catheter with the urethra. This suggests that there is a strong need for urinary catheter design to be improved to minimize mechanical interaction, especially mechanical damage to the urinary tract, and to enhance patient comfort. Several urinary catheter design directions have been proposed based on tribological principles. Among the key recommendations is that catheter manufacturers develop catheter coatings which are both hydrophilic and antibacterial, and which maintain their antibacterial patency for at least 90 days.

Caesarean hysterectomy

BACKGROUND

Caesarean hysterectomy is an obstetric emergency procedure performed to save maternal life in uncontrollable haemorrhage and few elective indications. It could be a planned procedure but more often it is an emergency operation.

OBJECTIVE

To ensure adequate exposure and mastery of this emergency procedure by residents in training in Obstetrics and Gynaecology in Nigeria.

METHODS

Review of the pertinent literature, selected references, and internet services through Medline search on caesarean hysterectomy.

RESULTS

The incidence for emergency caesarean hysterectomy is 0.01-0.05%. The maternal death rate associated with caesarean hysterectomy from all causes is 0.7% compared to 0.05% for all caesarean sections. Porro's operation was a subtotal amputation but opinion now favours a total hysterectomy where practicable. Inexperienced surgeons may encounter identification of the lower margin of the cervix as limiting factor, for fully effaced and dilated cervix. Subtotal hysterectomy may therefore be the more prudent, safest and fastest option, but the potential problems of a residual cervical stump must always be borne in mind.

CONCLUSION

Caesarean hysterectomy though a rare procedure is a life saving obstetric emergency. There is need for adequate exposure and mastery by the residents and a must for all obstetricians in their practice.

Servicemembers' Group Life Insurance Traumatic Injury Protection Program--genitourinary losses. Final rule

The Department of Veterans Affairs (VA) is issuing this final rule that amends the regulations governing the Servicemembers' Group Life Insurance Traumatic Injury Protection (TSGLI) program by adding certain genitourinary (GU) system losses to the TSGLI Schedule of Losses and defining terms relevant to these new losses. This amendment is necessary to make qualifying GU losses a basis for paying TSGLI benefits to servicemembers with severe GU injuries. The intended effect is to expand the list of losses for which TSGLI payments can be made. This document adopts as a final rule, without change, the interim final rule published in the Federal Register on December 2, 2011.

A modified LAVH to reduce urinary tract injuries: 102 consecutive case-series at Srinagarind Hospital, Khon Kaen University

OBJECTIVE

To describe the technique and results of modified laparoscopically assisted vaginal hysterectomy (LAVH), especially, on the urinary tract injury.

MATERIAL AND METHOD

One hundred two patients scheduled for modified LAVH between November 2007 and December 2010 were enrolled.

RESULTS

The majority of patients were middle-aged. The median parity was two; 16 patients were nulliparous. Among the 39 patients who had undergone prior abdominal or pelvic surgeries, eight had a prior cesarean delivery. The majority of LAVH indication was leiomyoma with complications. The median uterine weight was 300 g (range 120 to 1,450 g). The median operating time was 105 min (range 50 to 365 min). One patient had repeated laparoscopic uterine artery electrocoagulation 12 hours after surgery. Two patients were re-admitted with pelvic inflammatory disease (PID) two to three weeks post-operatively. No bowel or urinary tract injuries were detected during intra- and post-operation.

CONCLUSION

The modified LAVH presented here was a technique that showed a low incidence of urinary tract injury.

Renal function abnormalities after marathon run and 16-kilometre long-distance run

Renal functions were investigated in 29 marathon runners and in 20 runners in connection with 16-kilometre long-distance run. Body weight in runners decreased after marathon run in average of 1.3 +/- 0.5 kg and after 16-kilometre long-distance run in average of 1.4 +/- 0.4 kg. Blood pressure decreased after both runs. Total proteinuria and albuminuria significantly increased after both runs. The significant non-glomerular erythrocyturia was found in 9 runners after marathon run and in 3 runners after 16-km long-distance run. Total catalytic activity of serum creatine kinase, and its isoenzyme MB significantly increased after both runs. Increase of isoenzyme MB creatine kinase after runs was lower than 6% of total catalytic activity of creatine kinase. These increases were caused by rhabdomyolysis and were connected with myoglobinuria. Serum myoglobin significantly increased after marathon run and after 16-km run. Serum urea, creatinine, phosphorus and osmolality significantly increased after both runs. Calculated GFR significantly decreased after both runs. FE(Na), FE(Ca), FE(P), FE(OSM) and FE(H2O) significantly decreased after both runs. FE significantly increased after marathon run, but after 16-km run non-significantly decreased. Renal function abnormalities were caused by dehydration, microtraumas in extrarenal urinary tract, protein catabolism, decreased urinary excretion of osmotically active substances, rhabdomyolysis, activation of renin-angiotensin-aldosterone system and other factors. Renal function abnormalities in runners were already not present 2-6 days after marathon run and after 16-kilometre long-distance run and investigated parameters were in normal range or they did not significantly differ from the initial values.

[The closed injuries of the lower urinary tract: problems of the X-ray diagnostics]

The closed injuries of the lower urinary tract: problems of the X-ray diagnostics. Results of X-ray investigation were analyzed in 54 patients with urinary bladder trauma and 23 patients with urethral injuries. There were no false conclusions during urography in 23 patients with urethral injuries. In one patient urography was carried out in late terms due to the underestimation of urether trauma by the time of admission to the hospital. Cystography was carried out in 38 out of 54 patients to exclude bladder trauma. Presence of trauma was confirmed in 36 (94,7%) cases. False conclusion about the absence of bladder rupture was given in 2 (5,26%) cases. Type of rupture was misdiagnosed in 5 (13,1%) patients leading to increased extent of operation in 1 case. The reasons for the false conclusions were misconduction of investigation technique and underestimation of the obtained X-ray data.

Urinary complications of gynecologic surgery: iatrogenic urinary tract system injuries in obstetrics and gynecology operations

OBJECTIVES

To evaluate iatrogenic urinary tract system injuries in obstetrics and gynecology operations and compare the results with the literature.

PATIENTS AND METHODS

We examined the records of patients who had obstetric and gynecology operations at the Ministry of Health, Dr. Zekai Tahir Burak Women's Health, Training and Research Hospital between June 2007 and June 2010. All the patients who were diagnosed as having urinary system injuries in either the intraoperative or postoperative period were determined.

RESULTS

During this period, 25,998 gynecologic and obstetrical operations were performed, 0.03% ureteric, 0.20% bladder, and one case of urethral injury, in a total of 0.24% urinary tract injuries were observed. The bladder was the most frequently injured organ. Total urinary tract injury rates were 0.79% (0.49% bladder, 0.24% ureteral) in gynecologic operations and 0.19% (0.18% bladder and 0.01% ureteral) in obstetric operations.

CONCLUSION

Urinary system injuries are seen in approximately 1% of all gynecologic and obstetric surgeries. The complication rates observed in our patients were comparable with the other studies in the literature. A gynecologic surgeon must become familiar with the anatomy of the urinary tract and must be aware of common intraoperative and postoperative complications to decrease the risk of morbidity.

Assessment and initial management of urologic trauma

This article discusses the appropriate assessment, initial management, timely referral to a urologist for abdominal, bladder, urogenital, and renal/renal collecting system injury. Appropriate laboratory and physical examinations, as well as radiologic imaging, are paramount to obtaining accurate diagnosis and to providing appropriate treatment.

Percutaneous radiofrequency ablation of renal tumors in solitary kidney patients

OBJECTIVES

In solitary kidney patients with renal cell carcinoma (RCC), radiofrequency ablation (RFA) could be effective in achieving complete tumor necrosis without increasing the risk of complications or renal failure. To analyze the outcomes of a group of solitary kidney patients treated for RCC by RFA considering tumor size and location, renal function involvement and complications.

METHODS

A transversal retrospective study was performed, in which we selected 11 solitary kidney patients with 19 tumors in total treated by RFA for one or more renal tumors. A CT protocol was used for follow up. It included unenhanced series and contrast enhanced series at 1 month, 3-6 months, 12 months and yearly after RFA. Serum creatinine levels of each patient, pre RFA and within the first 48 hours after RFA, were collected.

RESULTS

Complete ablation was achieved in 17 tumors (89.4%) after one or two RFA sessions. 100% of exophytic and parenchymal tumors, and 3 cm size or smaller, were completely ablated. Renal failure, immediate complications or more than 24 hours hospitalization were not observed in 10 (90.1%) of our patients.

CONCLUSIONS

RFA treatment for RCC in solitary kidney patients has a high success rate; it does not affect renal function and achieves complete initial tumor necrosis, especially in exophytic, parenchymal and 3 cm or smaller lesions.

[Pelvic injury from the urogyneacology point of view. Overview]

The authors completed all available information of the national and foreign literature concerning problems of urogynecological injuries associated with a pelvic injury in women with regard to possible consequences to the quality of life. The authors also aimed their attention on potentional risks associated with pelvic injury in pregnant women. Urological and sexual disorders following pelvic injuries in women in the fertile age represent a separate chapter of traumatology. Increase in these injuries noticed in last years requires particular attention to diagnostics and treatment of these conditions: urinary incontinence, sexual disorders and pregnancy in women who suffered a pelvic injury. The problem of diagnostics and sequelae of injury of the pelvic floor still remains unresolved.

Determinants and complications of emergent cesarean hysterectomy: supracervical vs total hysterectomy

OBJECTIVE

We sought to determine whether emergent cesarean supracervical hysterectomy is associated with reduced risk of complications compared to total hysterectomy.

STUDY DESIGN

We conducted a cohort study of 150 women who underwent emergent cesarean hysterectomy at our medical center from 1991 through 2008. We compared the risk factors and indications, and intraoperative and postoperative complications associated with the 2 surgical procedures.

RESULTS

During the study period, a total of 164 cesarean hysterectomies were performed; 91% (n = 150) of these cases were performed emergently of which 53.3% were total and 46.7% were supracervical. There was a significant decline in the relative frequency of total hysterectomy: 71%, 56%, and 24% during 1991-1996, 1997-2002, and 2003-2008, respectively (P < .001). Risk factors, indications for surgery, operative variables, and postoperative complication rates were independent of the type of hysterectomy.

CONCLUSION

Using a cohort of 150 cases from our institution, we found no evidence of increased surgical time or complications associated with total hysterectomy.

[Sports and genitourinary traumas]

INTRODUCTION

Statistical data referring to sports-related traumas of the urinary tract are quite scarce; nevertheless, it is possible to draw general data on the relationship between sports and urological traumas.

METHODS

Literature review of peer-reviewed articles published by May 2009.

RESULTS

Urological traumas account for about 10% of all traumas, and about 13% of them is sports-related. Genitourinary traumas are among the most common cause of abdominal injuries in sports. Blunt injuries are more common than penetrating ones and renal injuries are by far the most common, followed by testicular injuries; ureters, bladder and penis injuries are much more infrequent. Considering chronic microtraumas, injuries of bulbar urethra are also common in sports that involve riding. Overall, the incidence of genitourinary trauma due to sports is low. Renal traumas in sports injuries usually consist of grade I-II lesions and usually do not require surgical treatment. Cycling is the sporting activity most commonly associated with genitourinary injuries, followed by winter sports, horse riding and contact/collision sports. Literature data suggest that significant injuries are rare also in athletes with only one testicle or kidney. General preventive measures against sport-related injuries, along with the use of protective cups for male external genitalia, are generally sufficient to reduce the incidence of urogenital trauma.

CONCLUSIONS

Overall, studies show that urogenital injuries are uncommon in team and individual sports, and that most of them are low-grade injuries. Participation in sports that involve the potential for contact or collision needs to be carefully assessed in the athletes with only one testicle or kidney, even though urogenital injuries should not preclude sports participation to an appropriately informed and counseled patient. Further research is needed to acquire more knowledge on genitourinary injuries according to age, sports type and technical skill.

[Accidents and incidents in gynecologic surgery]

Gynecologic surgery often entails meticulous dissection in areas close to the bladder, rectum, ureters and major vessels of the pelvis. The close anatomical relationship between these bodies that frequently makes are affected during pelvic surgery. When a complication occurs, it is vital to recognize and treat appropriately, emphasizing that gynecologists should handle its own complications and when they exceed the capacities of their own specialty, as in the case of unusual or complex lesions, should be sent assistance of a colleague in another specialty to solve the problem. To avoid intraoperative or injury is very important to timely diagnose an adequate knowledge of anatomy, surgical techniques using methodical and meticulous, with delicate sharp dissection and manipulation of tissues with a high index of suspicion constant in addition to routine cystoscopy after surgery to rule out injury. Once diagnosed the injury, repairing it at primary surgery is usually easier, successful and results in less morbidity.

Urological trauma after gynecological and obstetric surgeries

OBJECTIVE

Gynecological and obstetric surgeries are not uncommon causes of iatrogenic injury of the urinary tract. Herein, we retrospectively report our experience with these injuries over the last 18 years.

MATERIAL AND METHODS

Between 1985 and 2003, 120 females (mean age 34.2+/-13.7 years) were included in this study. The types of injury were as follows: vesicovaginal fistula, n=90; ureterovaginal fistula, n=14, ureteric ligation, n=13, vesicouterine fistula, n=2; and ureterouterine fistula, n=1. Definitive repair of such injuries was performed in all cases, including 10 cases of recurrent vesicovaginal fistulae which were treated by means of augmentation cystoplasty or urinary diversion. All patients were evaluated regarding the time and type of surgical intervention and early and late postoperative complications, including failure of primary repair.

RESULTS

Of the 80 cases of vesicovaginal fistulae treated with definitive repair, 12 (13.3%) showed recurrence of the fistula. Early ureteric deligation and early or delayed ureteroneocystostomy or ureteric replacement were successful in all cases with ureteric injury. There was no loss of kidney function following the trauma or its repair.

CONCLUSIONS

It is mandatory for gynecologists and obstetricians to pay careful attention to the anatomy of the urinary tract in order to avoid its iatrogenic injury. Endourologic means were successful in enabling first aid management of some of these injuries. Early exploration is indicated in cases of ureteric obstruction that present early after trauma. Augmentation cystoplasty, urinary diversion or ileal replacement are indicated in only a few cases.

[Urinary tract trauma: anatomo-lesional, etiological and clinical considerations]

Urinary tract injuries are rare lesions and account for about 3%, of all injuries and 10% of abdominal trauma injuries. The aim of this study is to review retrospectively a series of patients with urinary tract injuries treated in a general surgery clinic.

MATERIAL AND METHODS

A series of 41 consecutive patients with urinary tract trauma who hospitalized in Surgery Clinic of "St. John" Hospital of Iaşi during a 7 years period (January 2002 - December 2008). The main analyzed variable was age, mechanism of injury, anatomical site of injury, associated injuries, and methods of treatment, morbidity and mortality.

RESULTS

Urinary tract injuries accounted for 3.2% of all abdominal trauma injuries. Adults males were more affected with 90.2% of cases. Traffic road accident and falls represented over 50% of cases. Renal trauma were present in 73.7% of cases, and associated lesions were present in all cases. Conservative treatment was applied for 24 patients (58.5%), nephrectomy (total or partial) was performed in 9 cases, suture of the urethra 1 case, suture of the urinary bladder 5 cases and cystostomy in 3 cases. Conservative treatment failed in 24 cases (58.5%), urinary complications were present in 8 patients (19.5%) and one patient died due to associated lesions.

CONCLUSIONS

Urinary tract injuries are rarely encountered in trauma settings, to a high index of suspicion is necessary to establish the diagnosis. Renal trauma is the most fervently lesions and conservative treatment represent feasible solution for these.

Proposed mechanisms of lower urinary tract injury in fractures of the pelvic ring

OBJECTIVE

To investigate whether the observation of particular pelvic fracture patterns enables the clinician to predict the presence and type of injuries to the lower urinary tract, as the mechanisms of injury to the lower urinary tract in association with fractures of the pelvic ring are unclear.

PATIENTS AND METHODS

The case-notes and radiographs of 168 patients with either pelvic ring or acetabular fractures were reviewed; 108 pelvic ring fractures (81 men, 27 women) and 60 acetabular fractures (46 men, 14 women). The pelvic fractures were classified according to the system described by Tile and were correlated with the incidence and type of lower urinary tract injury (LUTI).

RESULTS

Overall, of the 108 men and women with pelvic ring fractures, 27 (25%) had a LUTI documented either radiologically or as an intraoperative finding. Of the 81 men with pelvic ring fractures, 24 (30%) had a LUTI, of whom six (7%) had an isolated bladder laceration, 14 (17%) a partial urethral injury (PUI) and four (5%) a complete urethral disruption (CUD). Five of the 18 men with urethral injuries also had bladder injuries and in three of these, the bladder neck was also injured. Three of 27 women (11%) had a LUTI, all of whom had isolated bladder lacerations. Of the 46 men with an acetabular fracture, one (2%) had a CUD, and three (7%) had a PUI. One of 14 of women with an acetabular fracture sustained a bladder laceration. None of the three men with a Tile Type-A pelvic ring fracture sustained a LUTI. Of the 28 men with 'open-book' (Tile Type-B1) fractures, 21 (75%) had no associated LUTI and seven (25%) had a LUTI (five partial urethral injuries and two bladder lacerations). Of the 10 men with 'lateral compression' (Tile Type-B2) fractures, six had no LUTI and four had a LUTI (two partial urethral injuries and two bladder lacerations). Of the 40 men with 'vertical shear' (Tile Type-C) fractures, 27 (68%) had no LUTI and 13 (32%) a LUTI (four complete urethral disruptions, seven partial urethral injuries, and two bladder lacerations) including all of the combined bladder and urethral injuries and all of the bladder neck injuries.

CONCLUSION

The pelvic fracture pattern alone does not predict the presence of a LUTI. When it occurs, the type of LUTI appears to be related to the fracture mechanism. The pattern of injury to the soft tissue envelope and specifically to the ligaments supporting the lower urinary tract offers the best correlation with the observed LUTI. We propose a mechanism for this.

Emergent and Surgical Interventions for Injuries Associated With Eroticism: a Review

BACKGROUND

To review the consequences of sexual activities that can cause severe morbidity and the current emergent and surgical measures for treating them.

METHODS

A computerized search of the English and non-English MEDLINE database (January 1973 to October 2005) identified the major sexual activities that caused injuries requiring emergent or surgical intervention, or both. These activities were grouped by type, pathologic findings, and sites of injury. Cause and symptoms are discussed, as are the radiologic, emergent and surgical interventions employed worldwide.

RESULTS

Two major groups of sexual-erotic activities, whether self-inflicted or accidental, emerged as culpable for most of the injuries. One was hetero-homosexual relations that were associated with penile fracture and Peyronie's disease. The other was related to the sequelae of autoeroticism and included penile constriction devices, anorectal, urethra-bladder, and vaginal foreign bodies as well as autoerotic asphyxiation. Injuries in both groups affected men more than women (e.g., 1.7:1 for foreign bodies in the urethra and 99:1 for anorectal). Complications were either immediate or delayed. Predisposing factors for injury are described. Emergent medical management and corrective surgical measures (usually by urologists and gynecologists for genital involvement and proctologists and general surgeons for rectal involvement) were similar worldwide and the need for them was surprisingly limited.

CONCLUSIONS

Most erotic activity-related injuries are medically or surgically treatable, although some sexual practices can be lethal. Dissemination of information on risk of injury is the best preventive measure.

[Surgical treatment of iatrogenic lesions of the urinary tracts and their complications]

The article presents results of surgical treatment of 167 patients with iatrogenic urinary tract lesions made in the course of various surgical interventions. Ureteral trauma was detected in 106 (63.5%), urinary bladder trauma--in 44 (26.3%), urethral trauma--in 5 (3.0%) and trauma of the bladder and ureters--in 12 (7.2%) patients. Endoureterotomy was made in 7 (4.0%) patients with short ureteral stricture, intraoperative correction of ureteral injuries was made in 8 (4.6%) cases. Ureteroplasty according to the technique designed by the authors was conducted in one female patient. A variant of ureterocystoanastomosis (UCA) was created in 67 (38.8%) patients. Reconstruction of the urinary tract with an ileal graft was performed in 16 (9.3%) patients, with the appendix--in 4 (2.3%) patients. Intestinal plastic correction of the ureters and urinary bladder was made in 2 (1.2%) patients. In trauma of the urinary bladder in 3 (1.7%) patients it was sutured, 41 (23.7%) patients underwent transvaginal vesicofistuloraphy. Electrocoagulation of the vesicovaginal fistula and colpocleisis were performed in 8 (4.6%) patients. Plastic surgery of vesicorectal and urethrovaginal fistula was conducted in 3 (1.7%) and 5 (2.9%) patients, respectively. In postoperative period after reconstructive operations complications developed in 17 (10.2%) patients. Conservative treatment of the complications was carried out in 11 (6.6%) patients, reoperations were made in 6 (3.6%) patients: resection of the stricture of appendicocystoanastomosis with reanastomosis (n = 1), repeat UCA (n = 1), revesicofistuloraphy (n = 1) and electrocoagulation of recurrent fistula (n = 3). Rehabilitation was achieved in 98.8% patients. Obstruction of the ureters and urogenital fistulas are prevailing complications (93.4%) of iatrogenic injury of the urinary tract. Operations of choice in such complications are UCA and transvaginal fistuloraphy, respectively.

Urinary tract injuries in patients with multiple trauma

This article mainly reviews urinary tract injuries in patients with multiple trauma. Approximately 10% of all traumatic injuries resulting from an external force will involve the genitourinary system. The article discusses mechanisms of injury, diagnosis, and therapeutical approaches for renal, ureteral, bladder, and urethral trauma. Due to the complexity of such injuries--despite several attempts to provide a standard strategy in trauma patients with urinary tract involvement--an individual and patient-specific-therapeutic approach is mandatory in most cases. However, the availability of classified guidelines may help the surgeon to reach the most accurate decision. Because of the similarity of American and European guidelines on urological trauma, this article adapts injury severity scales and classification from the American Association for the Surgery of Trauma.

Serum biochemical abnormalities in goats with uroliths: 107 cases (1992–2003)

OBJECTIVE

To characterize serum biochemical abnormalities in goats with uroliths.

DESIGN

Retrospective case-control series.

ANIMALS

107 male goats with uroliths and 94 male goats with various nonrenal diseases (controls).

PROCEDURES

For male goats, results of serum biochemical analyses collected from 1992 through 2003 were retrieved from computerized records, as were signalment, clinical diagnoses, and discharge status. Results of analyses for BUN, creatinine, phosphorus, calcium, Na, K, Cl, total CO2, anion gap, and glucose were compared between goats with uroliths and control goats.

RESULTS

Goats with uroliths had higher mean BUN, creatinine, total CO2, K, and glucose concentrations and lower mean phosphorus, Na, and Cl concentrations than control goats, with no difference in mean calcium concentration and anion gap. Goats with uroliths had higher frequency of azotemia, hypophosphatemia, hypochloridemia, and increased total CO2 and lower frequency of decreased total CO2 than control goats. Urolithiasis occurred more frequently in castrated males than in sexually intact males and in dwarf African breeds than in other breeds.

CONCLUSIONS AND CLINICAL RELEVANCE

Goats with uroliths often had hypophosphatemia at admission. Hypochloridemic metabolic alkalosis was the most common acid-base disorder. Rupture in the urinary tract system was associated with increased prevalence of hyponatremia and hyperkalemia. Clinicians should be aware of these abnormalities when determining fluid therapy.

Urinary tract injuries at caesarean section: prevention and management

This article focuses on predisposing risk factors and mechanism of injury for urinary tract injuries at caesarean section. Tips on prevention of injury are followed by a detailed discussion of the management options when injury occurs.

Urological injuries following gynecological operations--our experience in a teaching hospital in Nigeria

BACKGROUND

Various grades of urological injuries occur following gynecological operations. Some are recognized during or after surgery but others pass unnoticed.

AIMS AND OBJECTIVES

To study the urological injuries that follow gynecological operations in our centre.

DESIGN

Retrospective study.

SETTING

Nnamdi Azikiwe University Teaching Hospital, Nnewi Nigeria, a third generation tertiary institution serving rural, semi-urban, and urban communities.

PATIENTS AND METHODS

Searching through the records, all the gynecological operations performed in our centre from 1st July 1998 to 30th June 2003 were reviewed. Those patients in whom there were documented evidences of urological injuries were noted. Similarly, all the urological injuries treated in our institution during the same period but resulting from gynecological operations carried out in peripheral hospitals were also noted. From the relevant medical records, the following data were extracted: type of gynecological operation, nature of urological injury, time when injury was detected, status of the surgeon, management modalities, and outcome.

RESULTS

A total of 37 urological injuries occurred but, because of incomplete records in five, only 32 patients were included in this study. Ligation of the ureters following hysterectomy was the most common injury and occurred in 28 (87.5%) of the patients.

CONCLUSIONS

Ureteric ligation is a common urological injury following gynecological operations in our centre.

Current Recommendations for Imaging in the Management of Urologic Traumas

Three percent to 10% of trauma patients have genitourinary tract injuries. Radiologic imaging is essential for making the correct diagnosis and managing it appropriately. Which modality is appropriate is based on the mechanism of injury and patient presentation. Patients with pelvic injuries and gross hematuria should undergo either CT cystography or conventional cystography. Ultrasound is warranted in patients with scrotal trauma when physical exam is inconclusive. Patients with penetrating trauma to the external genitalia, who suffer blunt trauma to the penis, or who present with gross hematuria, blood at the meatus, inability to void, perineal/scrotal ecchymosis, or abnormal digital rectal exam should undergo retrograde urethrography. Using these criteria for imaging should lead to the proper diagnosis and minimize patient morbidity.

Rates of urinary tract injury from gynecologic surgery and the role of intraoperative cystoscopy

OBJECTIVE

To estimate the rates of urinary tract injury after benign gynecologic surgery. To explore the role of routine intraoperative cystoscopy at benign gynecologic surgery.

DATA SOURCES

We conducted a systematic MEDLINE search for urinary tract injuries at gynecologic surgery for the period from November 1998 to May 2004 and combined this with a previous systematic review performed in the same fashion for the period from January 1966 to October 1998.

METHODS OF STUDY SELECTION

There were 47 studies that fit our inclusion criteria: 29 that did not use routine intraoperative cystoscopy, 17 that used routine intraoperative cystoscopy, and 1 that reported the frequency of urinary tract injury separately, with and without routine intraoperative cystoscopy. We determined the crude and fitted ureteric and bladder injury rates for each surgery type from the studies where routine intraoperative cystoscopy was not performed and then from the studies where routine intraoperative cystoscopy was performed.

TABULATION, INTEGRATION, AND RESULTS

From studies without routine cystoscopy, combined ureter and bladder injury rates varied according to the complexity of the surgery, ranging from less than 1 injury per 1000 for subtotal hysterectomy with or without bilateral salpingo-oophorectomy to as many as 13 injuries per 1000 surgeries for laparoscopic hysterectomy with or without bilateral salpingo-oophorectomy and for other gynecologic and urogynecologic surgeries. Injury rates were higher when routine intraoperative cystoscopy was used, but the confidence intervals were wider.

CONCLUSION

The reasons for higher injury detection rates when routine cystoscopy was performed are unclear. Further study is needed to identify the scenarios where routine cystoscopy is warranted after major gynecologic surgery.

Hemostatic agents and tissue glues in urologic injuries and wound healing

Biosurgical preparations designed to promote surgical hemostasis and tissue adhesion are now available to the urologist and are increasingly being used across all surgical disciplines. Fibrin sealant and gelatin thrombin matrix are the two most widely used bio-surgical adjuncts in urology. Complex reconstructive, oncologic, and laparoscopic genitourinary procedures are those most appropriate for sealant use. This article details the diverse urologic applications of biosurgical products in the management of urologic injuries and the promotion of wound healing.

[Urinary tract injuries in polytraumatized patients]

BACKGROUND

Within the S3 Guideline Project of the European Association of Urology (EAU) an expert committee was set up to develop guidelines for the appropriate management of genitourinary trauma. These European guidelines were accepted in principle as national guidelines by the German Urological Society. Therefore, they also became the basis of the contribution of the German Urological Society to the S3 Guideline Project "Polytrauma" of the German Society for Trauma Surgery.

METHOD

For the guideline "management of genitourinary trauma" all the requirements for classification as S3 guidelines were full-filled. The guideline itself was developed in accordance with the principles of "evidence-based medicine". A systematic analysis of literature published between 1966 and 2004 was carried out. The articles retrieved were assessed in respect of study design and clinical relevance and classified following the scheme of the Centre for Evidence-Based Medicine in Oxford.

CONCLUSION

In suspected renal injuries the hemodynamic situation of the patient is the benchmark for the diagnostic and therapeutic algorithm. The diagnostic gold standard for the assessment of haemodynamically stable patients is CT scanning. Uncontrolled haemodynamic instability is an indication for immediate explorative laparotomy. Partial ureteral tears are managed by stenting; complete tears by immediate surgical repair. Pelvic fractures are often associated with bladder ruptures. Extraperitoneal bladder ruptures, identified by retrograde cystography, are in most cases safely managed by simple catheter drainage. Intraperitoneal ruptures require surgical intervention. Blood at the meatus may suggest a urethral lesion-blind urethral catheterization should not be attempted. Suprapubic cystostomy and delayed urethroplasty are recommended.
